I'm using this config that I found in this sub. https://github.com/toomuchio/plex-nginx-reverseproxy/blob/master/nginx.conf#L19 It fixed the problem I was having of idle timeout and cannot resume after a few minutes of being paused, but it feels noticeably slower. I'm using Let's Encrypt for SSL.

Any thoughts? Is it the Let's Encrypt that's slow?
