R7000 openVPN error

Hi All,
Please bear with me and my limited technical knowledge/skills....

I am trying to use openVPN with my R7000. I set up the VPN and download the setting files for mac os. And using Tunnelblick 3.6.8 (build 4625)  to connect the my network. However it keeps waiting for server response.

The logs:

*Tunnelblick: OS X 10.12.1; Tunnelblick 3.6.8 (build 4625)
