Xbox 360 all of a sudden stopped playing from Plex.

I have had my Xbox running Plex for the last two years. All of a sudden it stopped working and now I get a message when I try to play a video that there was an error communicating with the server. Nothing has changed! What is going on?

Same problem here. I received a mandatory update for Plex on my 360. Afterwards I was able to open Plex and see my vidofiles. But when I try to run them I get the message Server unvailable. On my second 360 I’ve the same issue. All other player on my network are functioning fine. The problem is somehow related to this recent update. Please advise on a resolution.

i’ve tried the usual. Sign out and back in. De- and resintall. All to no avail.

I am having the same issue. At points I can log out and log back in and communication resumes, but then it stops working. I can use plex fine with other devices such as roku, Vizio, android, etc. The only device experiencing issues is Xbox, all other see the server online.

Same thing here, I came to look for this problem. Some of the videos can be played and others say server is not avalaible, where as I can browse the server without problems. The same videos can be read from other devices without issues even outside of the network using Cell Carrier. This only occurs on the Xbox 360

I resolved the issue yesterday by downloading and re-installing the Plex SERVER. Try that and let me know if it works for you too

I’ve solved it. I bought a new PC, since my old server was about to die anyway. Installed the server all over again (version 1.1.4.2757-24ffd60) and now all 3 Xbox 360’s work fine again.
