They have the same range (192.168.0.x)Did you check that your old and new router were using the same IP-range?
If you look on the screen of your proxmox, it should show the IP, probably something like 192.168.1.22
If you go to your PC and check your IP, if the first 3 numbers (192.168.1.X) are the same, it should work, if not, probably the easiest method would be to change your router to be that range and then restart your PC afterwards.
It of course also can be done on proxmox (to have proxmox match the new range of the router), but a bit more tricky for someone (very) new to Linux.
My pc says package loss, and proxmox computer says destination unreachableok, can you at least ping the server, or if you log in on the screen of the proxmox server, can you ping the router and/or 1.1.1.1?
ip a
cat /etc/network/interfaces
yes one moment!ok, could you make / post a photo of the output of the following commands on the proxmox-console:
Code:ip a cat /etc/network/interfaces
