Internet connection doesn't work after a while.

Troubleshooting

Hi, I recently created a post in which I tried to solve a problem that after some time I couldn’t connect to the local network via ssh or web. I thought I’d fixed it but I haven’t. Now I can connect via ssh but the server has no internet connection. I’ve been frustrated for a month because I can’t get it to work, the dmesg command brings up this which may be related to the problem:

Hi,

how does network configuration looks like one your system is not able to access the web

ip a
ip r

It is connected by WiFi with the ip 192.168.1.110 without dhcp. The output that the commands show is:

but everything is working now. Correct? Or do you have issues to connect to the web right in this moment? I see as well you have a VPN interface tun0 running. Maybe you have issues connecting to the web because your VPN is not working correctly?

Sure enough, I use dietpi-nordvpn and right now I don’t have internet access. I have changed the vpn server and I already have an internet connection but I don’t understand why it randomly stops working. What can I do to avoid losing the connection using the vpn?

Most probably your VPN is failing and therefore you don’t have internet connection. It could happen that NordVPN disconnects. Just search the web, you will find a lot of entries on this. Maybe you should connect to this forum post. It’s a request how to automatically reconnect to NordVPN.
