Recently moved so setting up Sonos on new network. Some of our speakers (Beam, Move) we added with no issues. All our other speakers (another Beam, 5’s, 1’a, subwoofer) have been added to our network successfully. I can see them in the Sonos iPhone app - they show as “not registered”. They will not register with Sonos and I get the error message “There was a problem adding your Sonos 5 to your system. Try again later.” .
Any suggestions beyond resetting everything to factory settings or unplugging my router (all have been done several times with no success). appreciated.
