I made this : [ LINK REMOVED SINCE IT ENCOURAGES PIRACY ]
it's a tutorial that contains these instructions among others. (it's a tuto to install jellyfin with docker and to setup a raspberry pi with kodi to access it over wireguard)
(it's still WIP) but I discovered something odd. theses instruction work flawlessly on a RPI 4 but fail on Raspberry Pi 3 B+.
the script are the same. the config are correct and everything but the VPN just dont work. I can't ping the otherside of the VPN tunnel from the PI 3 (but I can access jellyfin from the PI4)
if you have a debugging suggestion or experienced the problem i'm all ears
