I am on Mac OS 10.7.5. My VPN connection has been unreliable for the past few days, and starting today, it simply times out being unable to connect. I have always generated an AirVPN access file using the OpenVPN Configuration Generator, then followed the instructions here to generate a Tunnelblick VPN Configuration. Once this file is generated, I would double-click on it and Tunnelblick starts fine. However, after I select the configuration from the menu bar icon, The Tunnelblick window continues to show only "Waiting for server response", then times out. Of note is that the same timeout issue is present even on my iPhone Would you please help me? Thank you.
