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 :)
