I am running the latest DIETPI software on a Raspi 4.
Some month ago I set up Wireguard and war rather proud to have my own VPN now. I only used it to use my home Internet connection, when I am abroad.
Since a while it doesn´t work anymore. And I have no idea where I should look and how I should start looking for a Failure.
Is there a kind of checklist I can through?
Many thanks in advance
