No products found

I’m not seeing the issue - do you have ‘background refresh’ enabled for the Sonos App on the iDevice? How long is the App left in the background before it’s brought back into main focus? 

Do you ever see the "no products found" message when the App is launched from a ‘fully closed’ state?

It maybe worth rebooting the mobile iDevice and perhaps consider resetting its network settings and setup the local WiFi connection again. 

If not doing so already, I recommend using the iDevice connected to the faster 5Ghz WiFi band, if available.

Do you currently have these things enabled?…

• ‘Private WiFi Address’ & ‘Limit IP Address Tracking’ enabled within the iDevice WiFi connection properties?
• Mobile Data Access for the Sonos App?
• WiFi Calling?
• VPN client/other security software running on the iDevice ?
• Firewall/Security Software enabled on the Router?

If so, perhaps see if toggling these things off, just temporarily, may help to resolve the issue.

See if closing all other open Apps might assist too and ensure the iDevice is not reaching storage capacity. If it is, perhaps try freeing up some space and see if that may assist.

If running your Sonos devices in wireless mode (recommended)  then next look at your Sonos device SNR levels as mentioned in this Sonos Support link…

https://support.sonos.com/en-us/article/understanding-the-network-details-section-in-the-sonos-app

Ensure your Sonos device SNR levels are set to 45dB, or higher, (if that’s achievable with your WiFi setup). In any event do not have them connected near or below 25dB … I would also recommend putting the Sonos products onto the 5Ghz band where that’s available/practical-to-do, aswell.

These Sonos products support a 5Ghz WiFi connection:

• Play:1
• Play:3
• Play:5 (Gen 2)
• Sub (Gen 1)
• Sub (Gen 2)
• Era 100
• Era 300
• Move 2
• Roam
• Roam 2
• Roam SL
• Five
• Move
• One (Gen 1)
• One (Gen 2)
• One SL
• Port
• Sub (Gen 3)
• Sub Mini
• SYMFONISK Bookshelf (Gen 2)
• SYMFONISK Floor lamp
• SYMFONISK Picture frame
• SYMFONISK Table lamp (Gen 2)
• SYMFONISK Bookshelf (Gen 1)

It’s also helpful to have the routers 2.4Ghz WiFi band using a ‘fixed’ non-overlapping channel 1, 6, or 11 and if the router allows, set that bands channel-width to 20Mhz only.

If using SonosNet, with device(s) wired direct to the main router ensure the wired device is set at least one metre away from the router and other wireless equipment and set its channel to one that is not in use by the local routers 2.4Ghz band.

Hopefully some things mentioned here may help to resolve your ‘products not found’ issue. However if the problems persist after exploring these suggestions, then it maybe best to reproduce the issue(s) seen and then immediately submit a Sonos system diagnostic report from within the Sonos App, note it’s reference and contact/chat with Sonos Support Staff via this LINK and see what the Staff can perhaps suggest to help you to resolve the matter.

I see the same behavior, but not just with the latest update. Although for me it doesn’t happen with every wake up from sleep.

The “Products not found” message usually only lasts a second or two. It frankly looks less like an error and more like a step in the app’s initialization process that unhelpfully displays that message rather than something like “Searching for your Sonos system...” -- like the Windows desktop app does -- or just saying nothing.

My iPad is running the 80.07.03 version. It’s connected to a stereo pair of Play:1s with the latest firmware. All three have a 5 Ghz, 20-foot, line-of-sight connection to the same access point. I’m not using this iPad and these speakers for anything except testing the latest updates. The rest of the house is still on S2 version 16.

I find it moderately amusing that the web player works better in this regard. It connects a bit faster to the same speakers with no misleading error message. For that matter, it does a neater job with volume adjustments and shows more things under “Recently Played”.

[Update] Wouldn’t you know it, but as soon as I said that, I started the web player again and it presented me with a message box saying “Your speakers are offline, please turn them on.” But then it went ahead and connected as soon as I closed that message box.

Fwiw, the speakers have SNRs of 60 and 62 dB.

Duplicate post removed.

If I leave my Home WiFi mesh system somewhat inactive overnight, the setup will switch to power saving mode and I then see the ‘no products found’ message flash up, albeit momentarily, on App launch (from fully closed state) first thing in the morning, but then it’s fine the rest of the day and I don’t see it when the App has been opened and is merely brought into focus from its backgrounded state.

In my own use-case I have ‘background activity’ enabled on my iPad & iPhone controllers for the Sonos App. The majority of my Sonos products are on the 5Ghz band with SNR levels of 45dB and higher. The suggestions made earlier are just some things that were aimed to make the connection between controller and players perhaps a bit more ‘snappy/responsuve’, but if no joy then see my latter paragraph to speak with Sonos Support about the matter.

I usually put my iPad to sleep by closing its cover, which has an auto-lock feature. If I immediately reopen it, the Sonos app is typically fine. But if I leave the iPad closed for a while, I often--but not always--get the brief “no products found” message when I re-open the app. I just reproduced that with a roughly one-hour pause between sleep and wake. Meanwhile, the speakers were playing continuously (from Amazon Music) and the web app was sitting open on my PC.

t feels like something in the app is timing out a few seconds too soon and throwing out an alarming and unhelpful message instead of a calming "Connecting to your system, please wait…" or even nothing at all.

Our WiFi is part of a Ubiquiti Unifi system with two non-mesh APs, one about 20 feet from my “office” area, which is just a corner of our open-plan basement. My APs are getting kind of old but are on current firmware. The speakers and the iPad are all connecting to that same nearby AP on the 5 Ghz band.

The other 11 speakers around the house are still running version 16 and they don’t show this flakiness. That includes the Beam (gen 1), Subwoofer Mini, and pair of Play:1s that I use for my PC right here in the same space. None of our speakers are wired to the network these days, so SonosNet isn't in the picture. All of the speakers are assigned fixed IPs.
