Hi,
I have been having this issue from the start of my server set up but was just trying to solve it with different ways but was unsuccessful so I ignored it for a long time but now I have decided I really want to resolve it.
So I am running plex in docker on ubuntu 22.04. I have plex Version 1.32.7.7621 this is the latest version. So the issue is when I ask alexa to play some content I would say “no plex companion players found” At first I thought It was alexa skill that was messed up. However i have notice something else to when ik try to cast something through plex mobile app to my fire tv or my Samsung smart tv to say no player found. i am pretty sure both of them are related. Any help is much appreciated. its just really annoying i hope somebody can help
