No internet connection: Temporary failure in name resolution

Hi @tbg thanks for your reply :slight_smile:

The router reboot did not lead to any changes.

Output of (ping -c5 google.com 2>&1) && echo “true”:

ping: google.com: Temporärer Fehler bei der Namensauflösung     (Temporary failure in name resolution)

I changed the resolv.conf with the given commands to the cloudflare ones, but ping google still shows the same result, also after restart of NetworkManager.service

It seems, I found the cause. I’m using Proton VPN with autostart for browsing safely, and the server region I was using seems to stopped working out of a sudden. As it didn’t show any specific error, I thought it can’t connect because of my Internet connection not establishing. Closing Proton VPN or switching to another server solved the problem.

Thanks a lot for the help and useful information/commands about resolv.conf.
