I recently installed Plex and signed up for the Plex Pass.
In doing so I went to Github and added serveral channels but none of them work. Everytime I go to watch something I get “This Channel Is Not Responding” or “No Content”
Im using a Macbook Pro, Chromecast 2.
Thank you
With above info, nobody can help you 
Go here to locate a support thread for a channel that is causing problems for you:
forums.plex.tv/discussion/200017/support-find-my-plug-in-here-for-support#latest
That way, people actually using the problematic channels, and maybe even the devs of it, could chime in
