Hello everyone, I am trying to pair my Roomba 505 to a Matter Server running on my Home Assistant. I am getting a connection through the Roomba app, the robot apparently goes into pairing mode, I am selecting my HA app on my Android and then it fails.
In the server logs, I am seeing this, ponting to some mDNS issue:

But I can't figure out what the issue is. As for mDNS forwarding, the network is flat and some other mDNS services are working fine. Looking in the discovered devices via DNS, I can see the IP addresses of my Roombas (DHCP won't change due to DHCP reservation...)
Does ansyohne have any ideas? Thanks Jens
