I have a Synology with DSM7, manually upgraded to the above server version. Plex works when streaming music (flac format) on the web client but does not work with sonos. I can browe the library but when I try to play music it gives the following error
Sunday, November 7, 2021 - 8:18 AM Eastern Time
Unable to play ‘Still’ - the connection to Plex was lost.
port forwarding for the server is setup correctly and I can play songs outside of my network.

I too am using Synology with DSM7 and getting the connection was lost error message. If I try multiple times it usually starts to play, the connection was lost message usually pops up even with it playing. Sometimes I do random play and it fails but just selecting play will sometimes start the random play mode. Once it starts to play I have no problems.
Exactly the same issue since early this year. Combo DSM7 with Plex on Sonos won’t play FLAC files giving the error ‘connection to Plex was lost’. MP3-files play without any issue.
Playing from my computer on the Plex web-interface, the FLAC files play without any issue.
Just upgraded Plex to latest package (1.25.2.5319-7000) without any improvements
Please Plex, how come this issue still is not resolved.?
Yep, I’m unable to play via my Sonos S1s too. In the Plex apps, it just skips, nothing obvious in the logs. If I watch the Sonos app while attempting to play I can see an error about connecting via IPADDRSSS.PORT.RANDOM.direct.plex (something similar at least) Remote access works fine, I double checked anyway just to be safe. I can play from Plex via the Sonos app and other devices can stream to Sonos fine. I’ve also disconnected and authorised the app.
It was plexamp mainly, however it was failing from all apps when I tried. I have just been playing around and disabling secure connections seems to have stopped the issue. Digging in deeper, I have disabled DNS rebinding on my firewall (opnsense) and re-enabled secure connections. It seems to be playing now, but they are in an outbuilding and I’m putting the kids to bed so I can’t actually hear it to check at the moment .
If it is the rebinding issue that’s odd as I’ve never changed that setting, it’s just been left as the default. I’ll need to look into a little more. Sorry about the possible false alarm, I check more once I’m able to. Thanks.
I have just updated to 1.25.6.5577 on my Synology NAS and I can’t get Shuffle All in my Sonos app to work at all. Same with both the Windows app and the Android app. Before it usually worked after several tries but now, I keep getting a message that the connection was lost. Before I sometimes would get the connection was lost message, but it would still start to play.

How do you redirect the Sonos App logs to my computer so that I can send them? Remember I am trying to get the Plex Shuffle command to work in the Sonos Windows app or the Sonos Windows App.
I have more success getting it to work when there isn’t any disk activity on the NAS.
From time to time the Shuffle playback will stop with the error message that the connection to Plex was lost, that is when I do get it working.
Oh you’re trying from the Sonos app. I thought you were using the Plex apps too. I have no idea how to get logs from the Sonos apps. Let me see if your server shows anything.
I have better luck getting the Shuffle All command to work if I select Shuffle All and then play now, I then get the connection was lost error message, I then use the play command and sometimes it starts to play, otherwise I repeat over and over until it does start to play.
Once I get it playing it almost always continues to work. I can pause and restart and it just works.
If I have the Sonos app open on my computer I sometimes get a message about 15 seconds before a tune ends that the next tune can’t be played and the connection to Plex has been lost. This may continue listing different tunes every two seconds until a tune is found that can be played. If no new tune is found before the playback is finished everything stops.
