Add remote-cert-tls server to config file. 

 

Remove error in the client at least.

    Thank you petieg1 ,

    I have done this step at #3 as you can see from my original response. It does pass the original error however fails in the next one. I'm thinking I might have some firewall i need to punch through. Will continue doing some more investigations.

      ho, yes.  Windows Firewall will definitely block the VPN.  Have to "add another program" to the Firewall rules.

      I did this with OpenVPN and also with Tunxten.  (trying different VPN clients)
