CRL has expired

@jimp I've just applied that patch and restarted OpenVPN. CRL expiry error no longer in OpenVPN logs and clients now connecting again - thanks !

You can install the System Patches package and then create an entry for
a3c1589086ea67d25a28ec14ab95d7fd9ab25fa2to apply the fix.We run into the same issue, lost all VPN connections.
Can we apply this patch also in 2.6.0 CE? -

The patch applies cleanly to 2.6.0, you can use it there.

@jimp
thank you, the VPN working again. -

Thank you all for the comments and patch solution here. Many of my haproxy backends went down last week (ssl handshake errors) and diagnosing the issue was very difficult.
A lot of trial and error, I narrowed down the backend SSL verification and CRL, as the culprit. I stumbled upon this issue after searching errors related to a downed OpenVPN client. Applying the patch here (obviously) fixed both haproxy and OpenVPN issues I was having.
Just wanted to add my experience in case any others are having the same issues with haproxy, and are looking for a solution. Hopefully they will also find this thread.

Thank you ! Worked like a charm on 22.05-RELEASE (amd64)
-
Same issue here. Patch solved it within a minute. Thanks.

I had the same issue with version 2.5 and 22.05, i wonder if netgate has permanent fix for that

Dear All,
Are we really really shure that the patch does fix this? I did apply it and it did work for the moment. After rebooting one of my four pfSense devices (2.6.0-RELEASE (amd64)), I was shut out of all of OpenVPN. The log did contain many entries like this:
Sep 1 18:09:39 openvpn 91912 xxx.xxx.xxx.185:31089 Certificate does not have key usage extension
Sep 1 18:09:39 openvpn 91912 xxx.xxx.xxx.185:31089 OpenSSL: error:1417C086:SSL routines:tls_process_client_certificate:certificate verify failed
Sep 1 18:09:39 openvpn 91912 xxx.xxx.xxx.185:31089 TLS_ERROR: BIO read tls_read_plaintext error
Sep 1 18:09:39 openvpn 91912 xxx.xxx.xxx.185:31089 TLS Error: TLS object -> incoming plaintext read error
Sep 1 18:09:39 openvpn 91912 xxx.xxx.xxx.185:31089 TLS Error: TLS handshake failedThe certificate did work before. After unchecking "Client Certificate Key Usage Validation", everything was OK again. Until the reboot today, it was no problem to leave "Client Certificate Key Usage Validation" checked.
Regards,
Michael

@michaelschefczyk I think that is a separate issue:
-
@ads76 Thank you very much. I did install the patches and I am "thrilled" to see what will happen next. I also hope that the system patches package will not become the replacement for regular system updates

Those are the changes on the patch

Is this patch still valid or have the changes for this now been rolled into the latest build?
-
Why ? You still use 22.05 from 2022 ?
These days, its 24.11 or 2.7.2 - I don't recall issues from 2022. -
@Gertjan No i'm using the latest version but this was still in my custom patches i applied - wasn't sure if i should remove it from custom patches or if I still need to keep it there.
-
@jagradang said in CRL has expired:

If it still shows applied - or: you can Revert it, then the patch isn't part of the version you use.
In that case : if it works for you, keep it ^^ -
@Gertjan perfect thank you. Still shows as applied and has the revert option so i'll keep it applied
