Wyoming Satellites won't reconnect with Home Assistant

Hi from Germany
In Feb. 2024 I configured 3 wyoming satellites using RPI3 and ReSpeaker 2-Mic Pi Hat.
They were connected to HA with Wyoming Protocol (Piper, Whisper, Openwakeword).
Music Assiastant Beta is configured too and they are all media players (snapcast).
One is still working in the kitchen as a Music Assistant player, the other 2 are configured, connected and used for testing only in February.
Voice recognition wasn’t as good as needed to be usefull.

Now I wanted to test them again and I’m not able to get them connected to HA with Wyoming Protocol. I deletet the services in HA and tried to reconnect, but won’t work.
HA doesn’t find them automatically and if I want to add a Wyoming host manually there comes the message: Connection failed.

They are still connected to Music Assistant as players and could be used.

The wyoming-satellite.service on the RPIs is running, the other services on the RPIs too.

Has somebody any idea, how to get them reconnected as Voice assistant clients in HA?
