core: Sonos not working, not discover or anything

Home Assistant release with the issue:

Last working Home Assistant release (if known):

Operating environment (Hass.io/Docker/Windows/etc.):

Component/platform:

Description of problem: Sonos doesn’t get discovered. Tried almost everything I bumped into on github and google. Nothing seems to work. I already removed discovery, added it back. Added it manual in various ways (configuration file, separate file for my mediaplayers,…). Also added the sonos.py script from here https://raw.githubusercontent.com/amelchio/home-assistant/30d5439a41bad9a88d55f9d5c51ccb281bdcfd23/homeassistant/components/media_player/sonos.py

hassio version 1.3.1

Also didn’t work… So, I’m out of ideas…

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

# The interface address is the address of the docker container interface
- platform: sonos
  interface_addr: 172.30.33.0
  hosts:
    - 192.168.86.70
    - 192.168.86.71
    - 192.168.86.98
    - 192.168.86.73
    - 192.168.86.74

Additional information: The config entry is the one I have now in my mediaplayers.yaml file ha.log
