[SOLVED] Certificate Expiration Date Issue

[sidney_v]

Hello,

I've 9 OPNsense in production, 1 of them is an OpenVPN Server and 8 others clients.
(it's a Peer to Peer SSL/TLS server mode)

Today, all clients had stopped working because of a server Certificate Expiration Date Issue 
Each client has a valid certificate generate by the server and the server itself has a certificate (<- this one is expired)

It's slowly going serious because I don't know how to extend expiration certificate date (best way) or how to generate another one properly for this kind of configuration.

Any help will be appreciated

EDIT: Mark as solved

System -> Trust

Create a new Certificate using the same CA and use this for the OpenVPN server.

Wow,

I've generated a new "Server Certificate" and now it works perfectly.
Thank you, you saved my life !

Have a nice day
