For some reason my Sonos app has a problem connecting to one of the three libraries I have on the Sonos app. Two of those libraries are remote (friends' accounts), and Sonos has no problem playing music from them. My own library is on my iMac in my home, and I can see all my music, playlists, etc., through Sonos, but when it goes to play a song, I get the message, "Unable to play 'song name' - unable to connect to Plex. I can play plex direct via my iphone and computer -- it's only through Sonos that it doesn't work, and only this particular library in my home. I have remote access enabled.
Are there any suggestions to get this fixed?
