Windows pc can't connect openvpn client behind speedfusion fusionhub

Trying to connect to datacenter private network using openvpn profile on windows PC. Windows PC is behind speedfusion VPN. OpenVPN on windows computer won’t connect this way with an error “TLS Error: TLSkey negotiation failed to occur within 60 seconds. TLS handshake failed.”

Is there a setting I should change/enable on peplink or fusionhub to allow the windows pc connected to it to make an outgoing openvpn connection?

If I add an outbound rule to route traffic from windows pc to openvpn server IP via wan1/wan2 instead of speedfusion, it connects fine. But I’d like it connect over speedfusion in case one of the wan links goes down so it doesn’t interrupt/disconnect.
