Long time Sonos user here and recently have been stuck on an 1101 update error that I can’t seem to get around. Have followed the instructions from Sonos, have rebooted all networking and Sonos devices, have tried updating from different iOS and PC controllers multiple times and over multiple days. Have turned off all IPS and firewalls and still no luck. Really quite frustrated. 

Any other suggestions? Everything plays fine, but there are some settings I would like to change that are grayed out (audio compression for example) and when I click on them it says an update is necessary, but it’s a vicious loop. 

Anybody, please?!
