I’ve been using Sonos and controlling it from my phone for over 1 year.  last week I receive a “netwrok problem detected” error when “I sign in to use new features” on the bar at the top of the app or when I check for updates in system updates.  I run an iPhone XR with iOS 13.2.  The Sonos is up to date.  The Sonos app runs correctly from other iPhones in my house.

      Wouldn’t it be nice if Sonos took this problem seriously? I’ve been torched with the same issue for several months now, no resolution at hand.

      The music services and sign-on refuses to work on my iOS device (iphone Xs iOS 13.3.1). Windows controller works fine. Using a visitors iOS device works fine. So obviously the problem resides on my  device itself, but nobody has been able to pinpoint it, including Sonos Support.

      Yes Cisco Security is installed but only Umbrella which should not be the issue (have also tried removing it, to confirm that). Furthermore I don’t use a VPN on my device in general, so that doesnt seem to be the issue either.

      Fresh ideas appreciated!

      I am having the same issue on iPhone XR iOS 13.4.1

      I looked at the Cisco support link above and Cisco says:

      “This issue will require a resolution from the Sonos side. Please contact Sonos support to add your support for a resolution.

      Cisco Umbrella has investigated this issue and confirmed that all DNS queries received by the CSC are answered without issue when the impacts occur. As a result, the issue is confirmed to occur in the OS layer between the DNS request and the transfer of this DNS query via the NEDNSProxyProvider Network Extension in iOS to the CSC with a component of the Sonos system currently in use.”

       

      Has there been any response from Sonos to this?

        Glad I found this. I have a business phone with Cisco on it. 
         

        Luckily I have an iPad so not an issue.

        My iPhone was getting the same network error while all my other devices were not.  I have “Circle” installed on my network.  It’s a firewall to monitor my kids internet.  I turned off circle and it solved the issue - I was able to log into my sonos account.  When I turned circle back on, I’m still logged in.  I disconnected my iPhone and sonos from the Circle network to be safe going forward.

          I had experienced the same issue despite of iOS version. Discovered that it was company VPN Zscaler that was blocking the Sonos app. When the Zscaler is disabled the Sonos app works just fine.

            For me was the opposite, I had to enable connection via Surfshark to be able to access the internet. Y power cycle everything with no result. So, since I se everyone disabling the VPN and I do not have those enable, I tried to enable it to see what happens, and it worked.  Usually I had this error with all my devices OSX, IOS, and android.  with the VPN  it works now. I will talk with my internet provider to see if they can fix the issue.
