My long running docker based home assistant setup seems to have lost the ability to discover my Sonos players. Everything was working a release or two ago and now I cannot seem to get any players into hass.
I clear out the Sonos configuration by deleting the integration and restarting. Sonos is discovered as a service and I click in the UI to enable the integration. I see this in the log:

The docker has 3 networks with the Sonos systems being on the main network 192.168.1.x/24. It looks like discovery is happening with 192.168.1.166 at least being discovered. But ultimately nothing appears in home assistant. No Sonos players are discovered.
