OpenVPN Certificate Expired, Now no phones will connect

The OpenVPN server certificate expired. I’ve stopped the OpenVPN Server, saved rebooted, enabled, saved and the certificate was re-issued for another 729 Days.

I went into EPN, re-built the phones configs and factory rest one of the phones… it boots up, gets the dhcp66 and connects, updates its firmware and connects. Then Set the phone’s config to use OpenVPN and save the settings… Phone receives it’s updated settings, reboots and then tries to connect to but it doesn’t complete the OpenVPN connection so it can’t grab it’s config.

What am I missing here?

After disabling the VPN server, deleting all the VPN clients, deleting an extension and it’s user, then recreating it all. Still no good. On the D62 phone under vpn settings I can see it has a config file but wont connect.

enabling the firewall on the PBX and then going to interfaces I see there is no interface for the VPN address as there used to be. Something is seriously wrong here.

The TUN1 interface doesn’t even exist on the server in system admin > network settings

Went to UCP, downloaded the OpenVPN config file… certs included are 0 bytes.

Looking in the /etc/openvpn directory, the certs are there but they are 0 Bytes as well:
