Sonos after a few hours unavailible

Configuration
1

Hello,

I have installed the sonos integration from HA.
my HA is in the 192.168.XXX.XXX network and the sonos speakers are in 10.20.XXX.XXX.
configuration.yaml looks like:

sonos:
  media_player:
    interface_addr: !secret ha_ip
    advertise_addr: !secret ha_ip
    hosts:
      - 10.20.XXX.XXX
      - 10.20.XXX.XXX #Küche
      - 10.20.XXX.XXX #Wohnzimmer
      - 10.20.XXX.XXX #Gästezimmer

but after a view hours the panels shows me that the sonos are unavailible and my logs in the webgui are empty…

after a reload it works for a few hours…

Can you help me please?

greetings
