Working here for me now.

Hi @Indrasentosa 

Welcome to the Sonos Community!

I recommend you make sure both the Sonos and Spotify apps are up-to-date, then reboot your phone/tablet and switch off your router and Sonos speaker(s). Once the router has been off for 30 seconds or more, switch it on and wait for WiFi to return before switching on Sonos again.

If you then still can’t connect Spotify to Sonos, try removing Spotify from Sonos and add it again:

Remove a music service account from Sonos

Add a music service to Sonos

If that doesn’t help either, I recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

Ive figured it put.

I connected to my JBL portable speaker.  

I can play all the music i want. 

Shame Sonos....  Shame

Hi @KBeaumont 

Welcome to the Sonos Community!

And thanks for the diagnostics - I was able to confirm that you’re being affected by a known issue that we are currently investigating.

Other than you perhaps needing to install a future update, this is up either Spotify or ourselves to fix - there’s nothing you’ll be able to do to fix the issue permanently. Some users have noticed an improvement after rebooting their entire Sonos system, however. I recommend taking the opportunity to reboot your router by removing power for 30 seconds too.

Edit: Or as you have already mentioned, play Spotify on Sonos from the Spotify app.

My friend, I'm only quoting you to inform that your signature, although allurring and seemingly intelligent, is wrong. Common sense is just like everything else in life, it exists and evolves. What may seem like common sense to an elder might seem like magic to a junior. It's a honed skill like any other, and evolution never stops.

I have same ”connection lost” problems too with all my music services. I have had Sonos products almost ten years without any big issues but last week I updated my Sonos systems from S1 to S2 and then these problems started. I regret that I made this update. I have 6 Sonos Ones, Sonos boost (which is wired to router) and Sonos Port. Before this update everything work fine. I just add Sonos Port to my systems and made this update to S2. Because of Sonos Port I can’t go back to S1. What about others, do you use S1 or S2?

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.

Guys, same frustrating problem here. Havent tried playing from the Sonos app for a couple of weeks. 

Instead, i have been using my system with Spotify connect. No problem with playback. I only use the Sonos app for grouping and EQ now. 

Im gonna keep doing this until Sonos confirms this issue is fixed. 

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?

It certainly suggests that the issue is on the Spotify end of things. If it was a Sonos problem, all other services would be equally impacted, as you point out.

Assuming that Sonos has received your diagnostics, and has identified the issue, I’m convinced that they have communicated the issue to Spotify. It would likely help if you were to also contact Spotify and complain. 

It’s unfortunate that Sonos doesn’t have any control over Spotify’s servers, and can’t work directly on them. Spotify has to do that work. All Sonos can do is point their service to the access point/server provided by Spotify.

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.

Depends on really what you mean….

You can always “group” speakers while playing music. They’ll play in sync.

In order to have surround speakers, it requires two speakers properly set up. 

It’s OK to be new, and ask questions. And there are specific definitions of certain words in the Sonos lexicon that have very specific meanings, such as “pair” “group”, “bond” and “room”. Probably some others I’m not remembering, but when these words are used in a Sonos forum, they do have very specific meanings. 

This issue with Sonos and Spotify is so frustrating. Have similar connection issues with Sonos Radio too. You pay lots of money for these speakers and so limited to the music and quality of music you get, so frustrating, we are capture as I have 3 of these speakers. Would not support anyone else buying Sonos! Software fix shoudl have been resolved years ago when this issue was first discussed. My fool me it seems to thing this supposedly quality product would resolve such a simple issue. Internet is not the issue which appears their fallback. 

This Spotify “connection was lost” issue is super annoying. It’s not happening with tunein, Apple Music, or Soundcloud. Sonos has to fix this! don't blame Spotify - you need to work together with Spotify to rectify this issue.

Funny thing is; I have three households and this issue only seems to occur in one of them. What is unique with the household with the issues? Cable-ISP (not fiber), Lots of networks around (but I have chosen the least busy channel for my SonosNet). Always Spotify having issues, not the other services.

Please help! My diagnostics no is 1150008154

Thx!

 If it doesn’t, I recommend you get in touch with our technical support team for some in-depth and real-time troubleshooting of your Sonos system.

Post deleted. See my reply below…

The Wife & I use both S1 and S2 Sonos Systems here at our Home, we have new and old Sonos products and so have both controller Apps on our mobiles.

By the way you didn’t have to upgrade to S2 for the Sonos Port, as that device is both S1/S2 compatible, as shown here in this Sonos Support Page:

https://support.sonos.com/s/article/4786

Anyhow @Pop74  the ‘connection lost’ issues you mention, will likely not be related to the Sonos S2 App (upgrade) as what you are more-likely experiencing here, sounds like a network-related matter perhaps arising from a router reboot, or change in WiFi/SonosNet channels.

Some routers will auto-select their WiFi channels on startup/reboot or their DHCP server can get confused when assigning IP addresses to multiple devices restarting at the same time across the LAN subnet.

I suggest perhaps trying this…

Set your routers 2.4Ghz WiFi band to use a ‘fixed’ non-overlapping WiFi channel, either 1, 6 or 11 and if the router allows set the channel-width to 20MHz.

If using SonosNet, then ensure you have one Sonos device only wired to the main router and set the SonosNet channel so it is at least 5 channels away from your chosen router channel. Also keep any wired product at least one metre away from the router.

Power off all Sonos products and the router and bring them back online in this order:

• Modem/Router 
• Wired Sonos Products
• Wireless Sonos Products (nearest to router, then next nearest etc.)

Let each device settle and connect to the internet before moving onto the next device.

Once all is setup and working then (optionally) consider adding your Sonos device IP addresses to the routers DHCP server’s reservation table as that should certainly help to prevent any further IP address conflicts going forward. HTH

There’s every chance you might encounter the same ‘connection lost’ issues now, even if you could revert back to an S1 System. You will ‘undoubtedly’ be far better off running all on S2 in the longer term… it’s probably just a case of sorting the Network issues here (I believe) …and my post above should (hopefully) go someway to help resolve those issues seen since the upgrade.

Seems a lot like a network issue, with the speaker in the kitchen not communicating properly with the wired Arc. Have you gotten in touch with the technical support team, as mentioned previously in this thread?

Sonos hasn’t changed anything on their side of the equation, to my knowledge. So it’s either an internal network change in your home, or an issue with Spotify. I’d 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.

Hello all, I have just set up a Sonos one in my kitchen on wifi and have an Arc in the living room that is hard wired into my router. I play Spotify through Sonos S2 app and …you guessed it ! the Sonos one looses connection and stops playing music. Where do I go from here if all above instructions fail to sort this issue out?

Thank you.

Glad to hear of your success with running from the Spotify app.  I was thinking it was a Spotify issue.  I’ll have to try that next time.

I'm having this issue right now and it's ridiculous. Song plays, song ends, next song doesn't play (connection to Spotify was lost). Song plays, try to skip, next song doesn't play (connection to Spotify was lost). 

If it is a Spotify issue, perhaps Sonos work directly with them to figure out what's going on if they haven't already. Also, updates on any progress on said issue would be very professional and customer friendly of them as well.
