Hello everyone!
My opkg update both thro LUCI and CLI doesn't wanna update, while my internet is getting routed fine.
It's outputting this error:

I have a setup like this where the MI4AG and LEDE routers are on 2.x and same submask (the LEDE has dhcp on, disabled that for the mi4ag)
They route the internet fine, I just cannot use opkg tho :/
Any tips? I'm assuming I'm just horrible at setting up this multi router setup I have, as I'm clueless regarding networking.
Any help is appreciated! Thank you!
