OpenVPN Support Forum

Here is the situation.
We have 3 Synology Diskstations in 3 remote locations, which can be reached by openVPN.
OpenVPN server is installed on the 3 Synology Diskstations (not on the router).
Our clients use openVPN connect v3 software to connect to these servers.

Everything has been fine until October 1, ever since then we can't reach 2 of the Synology servers with openVPN.
The error message we get is: Peer certificate verification failure.

But we don't use any certificate! We would simply click on: continue connecting without certificate.
We can't reach the servers, since the client or servers side can't verify the non-existing certificates?

I would appreciate any help, I can provide more information if needed.

I managed to solve the problem.
A newly installed Synology generates a certificate for itself, which works for about half a year. Then you need to renew it, I picked Let's encrypt certificate, which is valid for 3 months.
Now the clients can connect to the server.

THANK YOUUUUUUUUUUUUUUUUUUU
YOU SAVED MY LIFE
