VPN not working any more after reboot

StefanZ

Alright, so I had some time to experiment.

The OLD certificate [the one used by all the team members] will not be accepted for connections anymore.

I created a new one today and that works just fine on the same domainname.
Switching back to the original certificate: it stops working.

The certificate is still displayed as valid, but maybe the storage is somehow corrupted?

Hello @StefanZ
It looks like the original cert somehow corrupted after a restart, right? May I know your firmware version?

I would like to know more information about the cert as well. could you send me the original cert(corrupted) and the working cert? thanks.

current: V5.37(ABUI.2) / 2024-01-20 02:37:15

before was V5.37(ABUI.1)

One of our iMacs could no longer obtain an IP via DHCP on eth0, so I restarted the F200 (still on ABUI.1). After that, the VPNs that worked fine before failed. After that I updated the FW – which did not solve the problem. Will send the cert via PM

I cannot produce the issue on 5.37P1, and we haven't received a similar issue recently.
Please re-generate the certificate as a workaround, meanwhile, I will pay attention to this kind of issue.
