core: Sonos Speakers not found anymore

The problem

I have my sonos configured via the UI without manual Network configuration. Since the Update to 2021.7 my 2 speakers are not found anymore.

What is version of Home Assistant Core has the issue?

2021.7

What was the last working version of Home Assistant Core?

2021.6.6

What type of installation are you running?

Home Assistant OS

Integration causing the issue

Sonos

Link to integration documentation on our website

https://www.home-assistant.io/integrations/sonos/

Example YAML snippet

Configured vie UI

Anything in the logs that might be useful for us?

I tried to add the Speakers manual in the configuration:

sonos:
  media_player:
    hosts:
      - 192.168.5.91
      - 192.168.5.92

With this the speakers could be found again, but working not good. The Cover pictures are not shown anymore and the Players don't recognize what is playing now. All the logs appeared at the same time. 

I found this in the log:
Error requesting favorites from <SoCo object at ip 192.168.5.91>: HTTPConnectionPool(host='192.168.5.91', port=1400): Max retries exceeded with url: /MediaServer/ContentDirectory/Control (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f0331d4c520>: Failed to establish a new connection: [Errno 113] Host is unreachable'))

And that:
Sonos Schlafzimmer cannot reach [None], falling back to polling, functionality may be limited

And that:
