Sonos does no longer show up after v0.72.1

I am running with new Sonos config setting in some issues.

The discovery process comes up with a notification, but when I click the link the page for the integration never comes back.

I then used the specific setting for the Sonos config with dedicated host entries (as in the doc), but even then none of my Sonos systems show up.

I turn the logs to info level, but I cant spot anything in there.

Anyone having a hint what I could do to debug it (running HA 72.1 on a Raspberry Pi).

Cheers
