- This page contains a list of health checks errors. These health checks are periodically performed performed by Radarr and on certain events. The resulting warnings and errors are listed here to give advice on how to resolve them.
- The branch you have set is not a valid release branch. You will not receive updates. Please change to one of the current release branches.
- Newer versions of Radarr are targeted for .NET6 or newer. Mono builds are not provided nor supported starting with v4. v3.2.2 is the last version of Radarr to support legacy mono builds. You are running one of these legacy mono builds, but your platform supports .NET.
See the below entries for how to switch from unsupported, end-of-life mono versions to dotnet.
- Ensure your branch is correct for your docker maintainer and repull your container
- Simply update the Radarr Port with
pkg update && pkg upgrade - (Optional) Remove the mono package if you wish
¶ Fixing Standalone installs
Errors such as:
- Back-Up your existing configuration before the next step.
- This should only happen on Linux hosts. Do not install .NET runtime or SDK from Microsoft.
- To remedy, download the correct build for your architecture and replace your existing binaries (application)
- In short you will need to delete your existing binaries (contents or folder of /opt/Radarr) and replace with the contents of the .tar.gz you just downloaded and then update your service file to not use mono.
DO NOT JUST EXTRACT THE DOWNLOAD OVER THE TOP OF YOUR EXISTING BINARIES.
YOU MUST DELETE THE OLD ONES FIRST.
- The below is a community developed script to remove your mono installation and replace it with the .NET installation. Contributions and corrections are welcome.
- This assumes you are on the
master Radarr branch, so update the variable if needed - This assumes that Radarr runs as the user
radarr, so update the variables if needed - This assumes Radarr is installed at
/opt/Radarr, so update the variables if needed
¶ Currently installed mono version is old and unsupported
- Radarr is written in .NET and required Mono to run on very old ARM processors. Mono 5.20 is the absolute minimum for Radarr.
- The upgrade procedure for Mono varies per platform.
Mono is no longer supported starting in Radarr version 4.0
- Radarr stores its data in an SQLite database. The SQLite3 library installed on your system is too old. Radarr requires at least version 3.9.0.
Note that Radarr uses libSQLite3.so which may or may not be contained in a SQLite3 upgrade package.
- Rejoice, the developers have released a new update. This generally means awesome new features and squashed piles of bugs (right?). Apparently you don’t have Auto-Updating enabled, so you’ll have to figure out how to update on your platform. Pressing the Install button on the System => Updates page is probably a good starting point.
This warning will not appear if your current version is less than 14 days old
- This means Radarr will be unable to update itself. You’ll have to update Radarr manually or set the permissions on Radarr’s Startup directory (the installation directory) to allow Radarr to update itself.
Radarr detected that AppData folder for your Operating System is located inside the directory that contains the Radarr binaries. Normally it would be C:\ProgramData for Windows and, ~/.config for linux.
Please look at System => Info to see the current AppData & Startup directories.
This means Radarr will be unable to update itself without risking data-loss.
If you’re on linux, you’ll probably have to change the home directory for the user that is running Radarr and copy the current contents of the ~/.config/Radarr directory to preserve your database.
- The update branch setup in Settings/General is for a previous version of Radarr, therefore the instance will not see correct update information in the System/Updates feed and may not receive new updates when released.
- signalR drives the dynamic UI updates, so if your browser cannot connect to signalR on your server you won’t see any real time updates in the UI.
- The most common occurrence of this is use of a reverse proxy or cloudflare
- Cloudflare needs websockets enabled.
- Nginx requires the following addition to the location block for the app:
Make sure you do not include proxy_set_header Connection "Upgrade"; as suggested by the nginx documentation. THIS WILL NOT WORK
See https://github.com/aspnet/AspNetCore/issues/17081
For Apache2 reverse proxy, you need to enable the following modules: proxy, proxy_http, and proxy_wstunnel. Then, add this websocket tunnel directive to your vhost configuration:
If you have a reverse proxy under a subdirectory, the RewriteRule should include your basepath e.g.
If Radarr is not running on the same machine as your reverse proxy. Replace 127.0.0.1 with the appropriate IP address/DNS name of your Radarr app.
For Caddy (V1) use this:
Note: you will also need to add the websocket directive to your radarr configuration
- Review your proxy settings and ensure they are accurate
- Ensure your proxy is up, running, and accessible
- Your configured proxy failed to test successfully, review the HTTP error provided and/or check logs for more details.
- System time is off by more than 1 day. Scheduled tasks may not run correctly until the time is corrected
- Review your system time and ensure it is synced to an authoritative time server and accurate
- The following PassThePopcorn indexers have deprecated settings and should be updated.
¶ Mono and x86 builds are ending
- Mono and x86 builds are no longer be supported with v4. If you are receiving this error then you are running the mono version of the application or the x86 version. Unfortunately, due to increasing difficulty in development support for these legacy versions we will be discontinuing their support and thus releases for them going forward. Thus it is advised you upgrade to a supported Operating System that does not require neither x86 nor mono. You may also be able to explore using Docker for your needs.
- A properly configured and enabled download client is required for Radarr to be able to download media. Since Radarr supports different download clients, you should determine which best matches your requirements. If you already have a download client installed, you should configure Radarr to use it and create a category. See Settings => Download Client.
- Radarr was unable to communicate with the configured download client. Please verify if the download client is operational and double check the url. This could also indicate an authentication error.
- This is typically due to improperly configured download client. Things you can typically check:
- Your download clients IP Address if its on the same bare metal machine this is typically 127.0.0.1
- The Port number of that your download client is using these are filled out with the default port number but if you've changed it you will need to have the same one entered into Radarr.
- Ensure SSL encryption is not turned on if you're using both your Radarr instance and your download client on a local network. See the SSL FAQ entry for more information.
- Ensure IPv6 is disabled on the system if it is not functional
- Ensure a DNS server (e.g. pihole) is not rate limiting queries
- One or more of your download clients is not responding to requests made by Radarr. Therefore Radarr has decided to temporarily stop querying the download client on it’s normal 1 minute cycle, which is normally used to track active downloads and import finished ones. However, Radarr will continue to attempt to send downloads to the client, but will in all likeliness fail.
- You should inspect System=>Logs to see what the reason is for the failures.
- If you no longer use this download client, disable it in Radarr to prevent the errors.
¶ Enable Completed Download Handling
- Radarr requires Completed Download Handling to be able to import files that were downloaded by the download client. It is recommended to enable Completed Download Handling. (Completed Download Handling is enabled by default for new users.)
This error is typically associated with bad docker paths within either your download client or Radarr
An example of this would be:
- Download client: Download Path: /mnt/user/downloads:/downloads
- Radarr: Download Path: /mnt/user/downloads:/data
Within this example the download client places its downloads into /downloads and therefore tells Radarr when its complete that the finished movie is in /downloads. Radarr then comes along and says "Okay, cool, let me check in /downloads" Well, inside Radarr you did not allocate a /downloads path you allocated a /data path so it throws this error.
The easiest fix for this is CONSISTENCY if you use one scheme in your download client, use it across the board.
Team Radarr is a big fan of simply using /data.
- Download client: /mnt/user/data/downloads:/data/downloads
- Radarr: /mnt/user/data:/data
Now within the download client you can specify where in /data you'd like to place your downloads, now this varies depending on the client but you should be able to tell it "Yeah download client place my files into." /data/torrents (or usenet)/movies and since you used /data in Radarr when the download client tells Radarr it's done Radarr will come along and say "Sweet, I have a /data and I also can see /torrents (or usenet)/movies all is right in the world."
There are many great write ups: our wiki Docker Guide and TRaSH's Hard links and Instant Moves (Atomic-Moves). Now these guides place heavy emphasis on Hard links and Atomic moves, but the general concept of containers and how path mapping works is the core of these discussions.
See TRaSH's Remote Path Guide for more information.
For Linux ensure:
- If you're using an NFS mount ensure
nolock is enabled for your mount. - If you're using an SMB mount ensure
nobrl is enabled for your mount.
- Within the application, a root folder is defined as the configured media library folder. This is not the root folder of a mount. Your download client has an incomplete or complete (or is moving completed downloads) into your root (library) folder.
- This frequently causes issues - including data loss - and should not be done. To fix this change your download client so it is not placing downloads within your root folder. Note that 'placing' also includes if your download client category is set to your root folder or if NZBGet/SABnzbd have sort enabled and are sorting to your root folder.
- Please note that this check looks at all defined/configured root folders added not only root folders currently in use. In other words, the folder your download client downloads into or moves completed downloads to, should not be the same folder you have configured as your root/library/final media destination folder in the *arr application.
- Configured Root Folders (aka Library folders) can be found in Settings => Media Management => Root Folders
- One example is if your downloads are going into
\data\downloads then you have a root folder set as \data\downloads. - It is suggested to use paths like
\data\media\ for your root folder/library and \data\downloads\ for your downloads. - Review our Docker Guide and TRaSH's Hard links and Instant Moves (Atomic-Moves) Guide for more information on the correct and optimal path setup. Note that the concepts apply for docker and non-docker
Your download folder where your download client places the downloads and your root/library folder MUST be separate. *Arr will import the file(s) from your download client's folder into your library. The download client should not move anything or download anything to your library.
- The location your download client is downloading files to is causing problems. Check the logs for further information. This may be permissions or attempting to go from windows to linux or linux to windows without a remote path map.
- The location your download client is downloading files to is causing problems. Check the logs for further information. This may be permissions or attempting to go from windows to linux or linux to windows without a remote path map. See TRaSH's Remote Path Guide for more information.
- Radarr or the user radarr is running as cannot access the location your download client is downloading files to. This is typically a permission issue.
- A file accessible via a remote path map appears to have been removed prior to processing completing.
¶ Remote Path is Used and Import Failed
- Check your logs for more info; Refer to our Troubleshooting Guides
¶ Completed/Failed Download Handling
¶ Completed Download Handling is disabled
- (This warning is only generated for existing users before when the Completed Download Handling feature was implemented. This feature is disabled by default to ensure the system continued to operate as expected for current configurations.)
- It’s recommended to use Completed Download Handling since it provides better compatibility for the unpacking and post-processing logic of various download clients. With it, Radarr will only import a download once the download client reports it as ready.
- If you wish to enable Completed Download Handling you should verify the following: * Warning: Completed Download Handling only works properly if the download client and Radarr are on the same machine since it gets the path to be imported directly from the download client otherwise a remote map is needed.
- It's required that your download client retain its history of completed downloads until Radarr has imported them. If history retention is disabled then *Arr may not see the completed download before it is removed from the download client. Your download client should be set to keep (usenet) and pause not remove (torrents) downloads after completion: either indefinitely or for at least 14 days.
- Sabnzbd: Switches => Post Processing => Keep Jobs must be set to 14 days or greater OR be set to Keep All History
- Removing completed downloads from your client can be managed by Radarr and enabled via the download client settings in *Arr. Thus *Arr can ensure that your download client history is cleaned up.
- Simply put you do not have any of your indexers set to allow automatic searches
- Go into Settings => Indexers, select an indexer you'd like to allow Automatic Searches and then click save.
- Radarr uses the RSS feed to pick up new releases as they come along. More info on that here
- To correct this issue go to Settings => Indexers, select an indexer you have and enable RSS Sync
- Radarr requires indexers to be able to discover new releases. Please read the wiki on instructions how to add indexers.
- None of the indexers you have enabled support searching. This means Radarr will only be able to find new releases via the RSS feeds. But searching for movies (either Automatic Search or Manual Search) will never return any results. Obviously, the only way to remedy it is to add another indexer.
- None of the indexers you have enabled support interactive searching. This means the application will only be able to find new releases via the RSS feeds or an automatic search.
- Errors occurs while Radarr tried to use one of your indexers. To limit retries, Radarr will not use the indexer for an increasing amount of time (up to 24h).
- This mechanism is triggered if Radarr was unable to get a response from the indexer (could be caused DNS, proxy/vpn connection, authentication, or an indexer issue), or unable to fetch the nzb/torrent file from the indexer. Please inspect the logs to determine what kind of error caused the problem.
- You can prevent the warning by disabling the affected indexer.
- Run the Test on the indexer to force Radarr to recheck the indexer, please note that the Health Check warning will not always disappear immediately.
- The Jackett /all endpoint is convenient, but that is its only benefit. Everything else is potential problems, so adding each tracker individually is now required.
- Even Jackett's Devs says it should be avoided and should not be used.
- Using the /all endpoint has no advantages, only disadvantages:
- you lose control over indexer specific settings (categories, search modes, etc.)
- mixing search modes (IMDB, query, etc.) might cause low-quality results
- indexer specific categories (>= 100000) cannot be used.
- slow indexers will slow down the overall result
- total results are limited to 1000
- if one of the trackers in /all returns an error, *Arr will disable it and now you do not get any results.
- Add each tracker in Jackett manually as an indexer in *Arr
- Check out Prowlarr which can sync indexers to *Arr and from the Lidarr/Radarr/Readarr development team.
- Check out NZBHydra2 which can sync indexers to *Arr. But do not use their single aggregate endpoint and use
multi if sync will be used.
- This error is typically identified if a Movie or Collection is assigned a root folder but that root folder is no longer available.
- This error may also be if a list is still pointed at a root folder and that root folder is no longer available.
- If you would like to remove this warning simply find the Movie(s) or Collection(s) that is(are) still using the old root folder and edit it to the correct root folder.
- Go to the Movies (Library) Tab
- Table View & Enable the Path column then sort by path
- Create a custom filter with the old root folder path
- Select mass edit on the top bar and from the Root Paths drop down select the new root path that you want these movie to be moved to.
- Next you will receive a pop-up that states "Would you like to move the Movie folders to 'root path'?" This will also state This will also rename the Movie folder per the Movie folder format in settings. Simply select No if the you do not want Radarr to move your files
- Run the Check Health Task in System => Tasks
- Create a custom filter in Collections with the old root folder path
- Select the collections and from the Root Paths drop down select the new root path that you want these collections' future movies to be assigned to.
- Run the Check Health Task in System => Tasks
A mount containing a movie path is read only and is not writable by the user Radarr is running as.
The movie is linked to a TMDb Id that was deleted from TMDb, usually because it was a duplicate, wasn't a movie or changed ID for some other reason. Deleted movies will not receive any updates and should be corrected by the user to ensure continued functionality. Remove the movie from Radarr without deleting the files, then try to re-add it. If it doesn't show up in a search, check Sonarr because it might be a TV miniseries like Stephen King's It.
You can find and edit deleted movies by creating a custom filter using the following steps:
- Click Movies from the left menu
- Click the dropdown on Filter and select “Custom Filter”
- Enter a label, for example “Deleted Movies”
- Make the filter as follows:
Release Status is Deleted - Click save and select the newly created filter from the filter dropdown menu
- Typically this simply means that Radarr is no longer able to communicate via API or via logging in to your chosen list provider. Your best bet if the problem persists is to contact them in order to rule them out, as their systems maybe overloaded from time to time.
- Review System => Events filtered for Warning (Warning & Errors) to see the historical failures or check logs for details.
- You have Discord configured to use a Slack webhook. This is not advised and the native Discord functionality should be used instead. If you're receiving this that likely means you just configured this by following an outdated guide. Please advise the guide author to update their steps.

- Radarr uses rolling log files limited to 1MB each. The current log file is always radarr.txt, for the the other files radarr.0.txt is the next newest (the higher the number the older it is) up to 51 log files total. This log file contains
fatal, error, warn, and info entries. - When Debug log level is enabled, additional radarr.debug.txt rolling log files will be present, up to 51 files. This log files contains
fatal, error, warn, info, and debug entries. It usually covers a ~40h period. - When Trace log level is enabled, additional radarr.trace.txt rolling log files will be present, up to 51 files. This log files contains
fatal, error, warn, info, debug, and trace entries. Due to trace verbosity it only covers a couple of hours at most.
