Connection to Spotify was lost

No problem. The downside is that using the system does not feel as neat as it once did. I have to use two apps and the Sonos app never needs to connect to the player as Spotify connect does. So its more of a "hassle" now, but at least it plays well so far. 

Interesting that Sonos just made a change to allow hi-rez Amazon, 24 bit 48kHz to be played on select Sonos products.  Wonder if a bug was caused from that bit of code.

Really disappointed to see Sonos consider this closed. I have tried many solutions and none of them are a permanent fix - some may work for a time but all fail eventually.

This is obviously an issue affecting many spotify/sonos customers but Sonos look to be unwilling or unable to resolve

Now that Sonos have your money (considerable amounts!) they do not care about supporting you knowing that you will not change manufactures

Sonos you led the whole multi room music revolution. Stop sitting on your laurels and sort this issue!

Where you at, Sonos support? We need an update. 

In the meantime, did you try using your system with Spotify connect?

Something odd going on here? For years I've had rock-solid Sonos/Spotify performance. For the last few days, continual errors with connection to Spotify was lost. 

Everything works fine if using the Spotify app and connecting to the Sonos speakers that way, it’s just in the Sonos app. Some tracks play fine, some don’t and it seems to be the same tracks that continually refuse to play so that makes me think this isn’t a wi-fi connectivity issue. Anyone else?

Switched from Spotify to Apple Music within the Sonos App… and yesterday after hours playing without issues… the same problem arose, this time with Apple. This is just weird. Sonos, any comments?

I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

Since experiencing the same issue as you all have I’ve been back and forth with Spotify to try numerous things.

A clean (more thorough) reinstall of the Spotify app somehow did the trick for me. Perhaps you all want to give this a try since I really get your frustrations and Sonos hasn’t come with a solution at all….

Bestest of luck!

OK - I’ve been fighting this issue for months.  In the SONOS app (doesn’t matter if I’m on Mac, PC, or phone - behaviour is the same) I’d estimate Spotify tracks play successfully <10% of the time.  Otherwise I get the “lost connection” error driving you all nuts.  This is a huge problem for me as I only use Spotify for music.  I also had the experience over the years of this problem occurring once in a while, and the problem quickly went away.  Over the last year or so, it’s become a real problem.

I’ve been through the whole tech support thing with SONOS - troubleshooting suggestions included changing the wifi frequencies, channels, and mode, changing DNS, etc.  Rebooted all SONOS devices, rebooted router, deleted and re-created Spotify service connect to SONOS.  Same experience as many of you I’m sure, and similar to the advice from @Corry P above.  I don’t know the problem between Spotify and SONOS - but it has nothing to do with any of that.

As @dasherpr above, I signed up for the Apple Music trial, created that service in SONOS, and the tracks play with 100% success (I’ve not yet seen the errors creep into the Apple service).  It is interesting that if I try to play a track from Spotify and get the error, then play from Apple with no error - if I then go back to Spotify content, it works.  After a while, the lost connection error resumes.

Best answer still seems to be the one from @Corry P 6 months ago - there is a problem in the handshake/data transfer from Spotify to SONOS.  They know what the problem is, and have done for at least 6 months.  They’ve just not gotten around to telling us about it.

That did seem to make the playback from Spotify app to SONOS speaker work better - but has not changed anything about playing from within the SONOS app.
