Strange OpenVPN error

[valunthar]

I'm running into an odd error after setting up OpenVPN according to this post that I found http://blog.stefcho.eu/?p=492, and setting up the Windows 7 openVPN client as described on the setup page

Mon Jan 21 21:30:11 2013 SIGUSR1[soft,tls-error] received, process restarting</ip>

Any ideas on what might be going on?

Check your firewall settings, and make sure your Protocol (UDP or TCP) and Port Number are set correctly.
