A restart didn't help. I ran into a similar problem...once I received a fail connection for whatever reason, I couldn't connect again until I restarted my machine and restarted FM on the host machine.
Thanks Josh. It turns out I didn't need your solution. I had introduced a typo in the IP address in my subsequent attempts to log on. Once I corrected that, connection was fine. Your suggestion would have been worth trying if I was still having trouble. I put my MacBook Pro to sleep every night, only restarting infrequently.
I hate those typos...:robotwink:
