System not found issue only on Windows 10

Hi Chris, I've done all of this twice and have been using Sonos PC software on Win 8.1 for over a year.  Seems something is not right here 🙂 All my tablets and IOS/Android devices are working well

I was saying the new iOS can cause up issues. But if you've rebooted router then that would have cleared. When Apple iOS devices get new os a lot of times I have to forget wifi on device and then add back home wifi. Wouldn't hurt trying. If still not connecting it may be some new firewall issue although no others upgrading to 10 have mentioned.

I had same problem today and upgraded yesterday to Windows 10. Sonos controller cannot find system on the upgraded computer.

Have you tried connecting to your system by clicking 'Add a new SONOS system' and 'Connect to an existing system'?

Found my problem I had to twink a few settings in my McAfee 'My Network' settings and now is all good. If you use McAfee or another Security SW I suggest you look there to fix this issue. Best of luck,Brian

Yes, I had the same problem. Had to go into McAfee and "trust" a new network.

I'm having the same problem, but on a brand new laptop with Windows. I installed the app, and complete the setup process. In all cases, the app tells me that it connected, and as soon as I close the window, the screen says that it could not find my Sonos. So, conflicting messages. This happens whether I set up with an existing Sonos, a new Sonos, and even when it is hardwired.

Sometimes there is a trial version of security software (McAfee, Symantec, Kaspersky or similar) installed even on brand new PCs.
Another culprit could be Windows location awareness (service), that's the pop-up window after you connect the Windows PC to a wireless or wired network asking you to select if it's a 'public', 'home' or 'business' network.
If you happen to select 'public network' Windows automatically sets very restrictive firewall settings, the PC is pretty much locked down. Same applies if Windows decides this is an 'unidentified network' and/or does not detect the internet connection.
So check those settings to see if you are properly connected and at least 'home network' is selected.

Check your Mcafee settings. You have to trust the new Windows 10 network

This worked for me:D

Solved! - Right click on McAfee icon in your apps tray on the bottom Windows ten bar and 'Change Settings' - 'Firewall' - 'Internet Connections for Programs'

Find 'Sonos Desktop Controller'

Change 'Access:' Incoming and Outgoing drop down to 'Open to all devices'

Check 'Net Guard' - Off

Save all changes and exit McAfee

Close your Sonos application and when you restart it, all is good!
