I had https://pivpn.dev/ successfully running for a while withuot any issues. Then suddenly it stopped working. The configuration was never received on various devices. Unfortunately there was absolutely no information anywhere – no logs, search results returned big essays on OpenVPN.
There is a little handy command which can actually fix the issues in a moment.
Go to the VPN server and just run pivpn -d
Running the pivpn command with -d option fixes most of the issues.
Its diagnosis will be printed to the screen.
