Failed to create socket on UDP port 53

I also had the problem with port 53 and it did seem to be iTunes. Odd as it had been working with iTunes on for quite some time. It only started doing this a week or so ago. Restarting would fix things but then it would come back. Be nice to not have that conflict as iTunes is useful for me on the Mini ( where everything is). Since PlexConnect uses port 80, why should there be this conflict?

PlexConnect uses port 53 as well to reroute DNS requests coming from Apple TV.
Default port for DNS is 53 and that is what The aTV is using so can’t have the liberty to set it to another.

I have experienced the problems a couple of times on Mac oSX 10.8.4 when re-configuring (uploading the latest plex connect) and simply restart the PMS and all is fine.

Here is how I solved it.

However I knew I already had PlexConnect running though, but killing it off and the DNS and WebServers is not straightforward if you want to restart PlexConnect.

First find the process ID running on Ports 53 and 443 (assuming you have used the default ports for PlexConnect and HTTPS)

Then Kill them, here is how using Terminal.

sudo lsof -i -P | grep -i 53 ( do this first - it finds the process running on port 53

Look for the Python process running on UDP port 53 and note the Process ID, now kill that process ID in the next line here.

sudo kill -9 (kill off this port process you have just found)

 

sudo lsof -i -P | grep -i 443 ( do the same again for the HTTPS port 443)

Look for the Python process running on HTTPS port 443 and note the Process ID, now kill that process ID in the next line here.

sudo kill -9 (kill off this port Process)

 

Kill, the PlexConnect Host process in Activity monitor if it exists; (if you created a launch daemon to run PlexConnect on startup), if it does it will be running next to the Plex Media Server process, I had this running as a launch daemon, so it needed killing.

 

Now re-start PlexConnect in the same Terminal Window, assuming you are in the right directory folder.

sudo ./PlexConnect.py
