Comment 6 for bug 244081

Makario, what distribution are you using? According to the traceback, the port number that Entertainer is trying to connect to is already taken by something else that your computer is running.

I don't think that we have a mechanism for changing port numbers in the preferences dialog, but you could go to /home/makario/.config/entertainer/preferences.conf and try changing the backend_port number to something different.

I don't have much experience with ports so I'm not sure of the best way to debug your problem. But I'm pretty certain that the blocking is definitely your problem.

Hopefully this information is useful to you.
