Can no longer connect to Plex

Somehow I’ve managed to get Plexamp to connect to my Sonos Move speakers via my Android phone.

This kind of doesn’t make sense to me but this is what I did (but I’ve never had to do this in the past for Plexamp to work as it should):

I created a Static IP address for my PC which is where my Music Library sits. I disconnected my VPN.

I then went into my router and created a “Port Forward” rule using Port 32400. I then opened Plex on my PC and checked the box that says “Manually specify public port” (32400) and Plexamp worked streaming music from my PC via my Android phone to my Move Speakers.

I then went into my Sonos App and my Plex library appears there also.

At this stage, I’m not game to turn off my PC to fully test it!

Thanks.

I’ve never had to do anything like this in the past. Plex and Sonos used to work together fine until a couple of months ago, hence all the heartache mentioned on this and other forums.

Also having this issue. I know there could be a lot of causes for it, but I’m at a loss here
I have a dedicated IP from my ISP to get around the CGNAT, which is what makes my plex server remotely accesible. This works fine on the app.plex.tv website, on the mobile apps, etc. I’m able to use the server fine remotely with this static IP and hardcoded port, so it isn’t a networking issue

However after authorising plex with Sonos for the first time, no media items are visible in the app. It simply says “No content items available”. Neither plexamp nor the plex app itself show sonos as a player in the list either, so I’m at a loss with what to try.

I can play to the speakers just fine via spotify connect, as well as over the local network via Music Assistant (the Home Assistant addon) with my plex library (so that sort of works…?) but just not from any of the plex apps natively, nor the sonos app

Even when I try to search manually in Sonos it just says "An error occured with Plex trying again later", which tells me nothing? Descriptive error messages would be a good start. Even if a little vague. But better than this.

I use Plex and have had issues playing content on Sonos from time to time.   One thing that worked for me is to use the Sonos app’s search feature to look for content you know is in your Plex library.  This worked and the content was found.  I could then go back to browse my Plex library directly.

It’s worth noting that although both the plex local content server and Sonos are on likely on the same wifi network, the connection is likely through a cloud server.  Sonos connects to Plex just like any other cloud based music service, it does not use a special api to access content stored locally. I think this is a cause of a lot of issues that we sometimes see with Plex, that may not appear when using the plexamp app on the phone or other sinks.

I also would guess that the ‘no content’ error is likely on the Plex side of things. It makes some sense that plex does not have your content properly cache, or similar functionality, when it receives an api call to browse content.  The search api call perhaps does get the content refreshed on the Plex side, so that everything is now available regardless api call for content.

Sonos does seem to give my Plex set up maybe a little to less time to spin up to show content on the app. That’s when it says “no content available”.

Sadly I've tried searching for content I know exists and has been in the library for a while. It just always gives the same error. So it doesn't work from Sonos to Plex.

It also doesn't work in the reverse. Plex to Sonos. Sonos speaker groups don't appear in plexamp as a player

I have posted some instructions for what worked for me if people are still having problems.

The advice is appreciated. In my case I already have the port manually set and configured in my router with port forwarding. Combined with the static IP, remote access works perfectly fine, just Sonos is having issues.

Every other app works fine on everything, just Sonos doesn't work with Plex

Is this an acknowledged bug? What should one do? Is there a timeline on when this might be resolved?
