Tonight, I was trying to connect to a buddy’s computer using Hamachi.

Hamachi showed the connection should work…

However, when we would try to ping, we’d get errors like “General Failure” or “Timeout.”

Turned out I was using the program “Peerblock.” Don’t ask why.

I closed PeerBlock, and voila, everything is working correctly…

So if you are having issues with Hamachi, just make sure you are not running PeerBlock. If you are not, and are still having issues, they have a great online resource, available here.
