I have installed OctoPi on my Raspberry Pi 3B+, that is connected to an MKS GEN L v1.0 motherboard for my 3D printer (Ender 3 Pro). When I open my OctoPrint into a browser I can use it, but I wanted to install some plugins. First time I had an error that said my server was offline, after connecting my Raspberry to WiFi and setting up a static ip-address, I've connected my Raspberry to my main board, after that it said the status of OctoPrint was operational, so I expected it will work.
Sadly, it says that my installation doesn't have internet, so I still couldn't install plugins. I see that in the "connectivity check" my host is 18.104.22.168 and my port 53; I've pressed on test and there it said "server is unreachable".
What am I supposed to do?
