I set up sonos Arc and Sub + one*2 last year.
I tried reconnect Sonos One last week, then the App said I need to update. But it fails many times and I reset Arc and Sub.
The Arc works. It keeps failing again when I tried to connect Sub.
I tried reset the Sub, rebooting my router and connect the ethernet cable but the result is same.
Does anyone know how to solve this?
error code 30 and 1000
