Not working with newest plex media server version

[Murianwind]

With the newest plex media version installed (1.31.2.6739), mpv shim won't connect to either the plex windows client or web client. The "select a player" button lists plex mpv shim as connectable but when you click it nothing happens.

Not working with that build either. Still will work on Mobile, but Plex desktop app local to Shim doesn't work still. Shim console shows no connection attempt from the plex desktop app.

Hmm looks like you are on a Plex Pass beta version so the docker container I used for testing is not running it yet... Maybe I can build it manually.

[wonkymedz]

More then happy to keep doing testing and further logging for you :)

[iwalton3]

Alright I have version 1.31.2.6739 in docker now. I get a 404 on the /player/timeline/poll in the web client which is what the Plex server uses to proxy requests to MPV Shim through the web app and desktop app. You can use this user script to bypass the issue: https://greasyfork.org/en/scripts/398049-mpv-shim-local-connection

I am taking a look further to see if there is a possible fix or workaround.

Tests:

• Test TV via app.plex.tv - Fail
• Test Movie via app.plex.tv - Fail
• Test TV via local - Fail
• Test Movie via local - Fail
• Test TV via app.plex.tv greasemonkey - OK
• Test Movie via app.plex.tv greasemonkey - OK
• Test TV via local greasemonkey - OK
• Test Movie via local greasemonkey - OK
• Test TV via Android - OK
• Test Movie via Android - OK

I did some additional looking and didn't find anything. It seems the server is just returning a 404 error for an endpoint that is critical for normal functionality through the web app.

This has happened before, so maybe beta builds just often have this break? #24 (comment)

[wonkymedz]

Hmm wierd im on the public release channel too!

[deposted]

Can confirm that updating to the beta branch for Plex borked my setup. Been using the greasyfork script as a workaround. Thanks again for sharing it! I've tried downgrading to the stable branch but it seems that casting it to MPV shim doesn't allow for a successful connection on my W10 PC.

[arshpsps]

can cast to "plex mpv shim" when using the script but mpv doesnt open up. audio plays for some reason

[arlinsandbulte]

I am having this issue too. I think 90 is the same issue (I'm cross-posting to there).
And, I think this is an issue with the Plex Server. I cannot cast from the web client to Roku or "Plex MPV Shim".
Here is an issue on Plex support confirming, I think. https://forums.plex.tv/t/plex-web-flinging-casting-broken/837738

My Plex Server Version 1.32.5.7516
My Plex Web Client Version: Version 4.115.2

[arlinsandbulte]

Plex Server 1.32.8.7639 has fixed this issue for me!

[Jerrk]

It works for me as well on Plex server Version 1.32.8.7639

I can also cast from the Plex windows desktop client now in Version 1.83.1.4061-d3f45728

edit: restarted my computer and casting no longer works from the desktop app or the local webui, only through the app.plex.tv domain.
all the version numbers are the same
and while writing this edit it started working again...
not sure whats happening 🤷
