Hello, we are using Sohpos XG virtual firewall to connect VPN, it was working fine till few days before. Now on connecting we are observing error which states that "Policy mismatch error. Import a new policy for this connection." Please note that applied certificate was expired but it has been replaced with ne one, still observing this error.
Hi Muhammad,
Have you read the notes from the troubleshooting guide? You may also try to recreate the tunnel.

I think that this massege is misleading. If you look closer at the openvpn.log you see that the tunnel pakets cant be decrypted and the connection fails.

It dos not matter if there is an xg or a utm working as openvpn Server. Not each Windows ad PC has this problems. We see it very often at smb copies. After or during the copy the connection fails. We always find this message:
