17.1.9 kills VPN

[Julien]

Hi guys,
last day we update to 17.1.9 and everything went fine however today we've received that the users can't log in using the VPN
I remember this behaviour before and it was related to certificate on pfsense.
Can someone please advise ?

Do you also have a log from the client?

don't worry, tried to connect from lan and it worked before...

At client connection status "bytes received" stay at 0 bytes for each client

Good Catch, on the client side it shows that the SSL is expired.

Thank you for posting me there.
right now we has found the error.
the certificate is expired, means we have to create a new one and push it to all devices ? we can just renew the existing one and don't have to resent it to users ?

Thank you

Got it working after I changed the installation from openssl to libressl and leaving all the other settings like before.
Only the connected since time is not shown correctly, still shown for example as 5453
