Existing system not found

I lost my connection to Sonos.  Now, when I try to connect with my iPhone, I get the Existing System Not Found message and when I ‘press and release’ the button nothing happens.  When I try to access Sonos from my tablet I get the ‘Sorry, we can connect to Sonos’ message.  I’ve tried resetting the router: still nothing.  Any ideas?

The next thing I would try as a troubleshooting step would be to wire a Sonos device to my router (if I didn’t already have one wired) and to wire a different Sonos device (if one already wired).  Give it a few minutes to reconfigure then post back with the outcome.

Did you change anything? Might anything have received an update or restarted in some way?

Unplug all your Sonos gear from power. Reboot your router. When it’s fully restarted and wifi running, restart your speakers starting with whatever is plugged into your router, and waiting for each device to restart before powering up the next. 
 

This fixed it last time you had this problem. I’m guessing you haven’t yet set fixed ip addresses for your speakers?

    You’re right, unplugging all the Sonos gear, rebooting the router, and restarting the Sonos units worked for me in May.  Thank you for your help, then.  And now.

    This time, I‘ve unplugged everything, rebooted my router, and tried restarting my Sonos Boost.  I’ve done all this a few times, sometimes turning my phone off and restarting it as part of the process, sometimes deleting and restarting my Sonos app.  I have the Plume WiFI app and it will often show my Boost as online (as I’m writing this reply it was online at the start, and now it’s not).  And when I’ve reloaded the Sonos S1 Controller app it has indicated ‘Connected to your Sonos system’, but when I press Done it says ‘Unable to connect to Sonos Learn More’.  At one point the phone app directed me to push the ‘infiniti button’ on the side of the Boost.  Which I did.  And then I got the ‘Unable to connect to Sonos Learn More’ warning.

    You helped me in May.  Maybe you can again.  Thank you.

    Have you recently upgraded to iOS14?

    I did get a new iPhone recently.  I think that would mean, yes, I recently upgraded to iOS14.  Sonos was working with the new phone, until a week or so ago.

    So, I confirmed the settings on the Sonos S1 Controller app were enabled for Local Networks.  I deleted the app and reinstalled the app.  I unplugged my router, my Sonos devices and turned off my iPhone.  I turned the router on again, and then my phone and then my Sonos Boost.  My iPhone Controller app at first indicated I was connected to the Sonos system, but when I advanced to the next window I again got the ‘Unable to connect to Sonos Learn More’ warning.

    Anyway, no change...and no luck.  But I can confirm the Local Networks setting is enabled.

    Any other suggestions?

    I have exactly the same issue since yesterday. The App can’t find my Sonos system.

    I have verified the Local Networks access on my iPhone (iOS14). I have re-installed the app, rebooted the router etc. No luck.

      Thank you John B - that did the trick! :smiley:

      I have a system with 4 different speakers and a Connect. I took one of the speakers and wired it directly to the router and lo and behold, suddenly my App could connect to all my devices!

      One possible cause is that your phone was on the router’s 5GHz band, Sonos 2.4GHz, and your router doesn’t bridge the two (maybe).  If you can force your phone to connect to 2.4GHz you may find that you can disconnect from Ethernet.

      But if it is convenient for you to keep a speaker wired then I would recommend you do so.
