OpenVPN connection Problems

[hugolg7904]

All connection using OpenVPN report an error: Connection TimeOut, Cannont connect because of the following error(s): LOST CONECCTION TO SERVER: 1 Times.
We also are using an another client called WireGuard, an this client it´s working fine.
What can I verify?

If you have a CRL and used the default expiry (9999 days), it might be this.

This appears in the openvpn server log as something like:

VERIFY ERROR: depth=0, error=CRL has expired
