Cannot add HD HomeRun tuner

I am trying to add my HD Homerun tuner, and am having problems. The tuner worked previously, but then stopped functioning within Plex. It works fine with the Silicon Dust Software. The auto detection of the device within Plex is not working, and when adding the IP address manually an error stating “There was a problem adding the device” appears. The Plex Tuner Server.log file just repeats the following.

Gah. Nevermind, firewall was stopping communication.
