Valetudo MQTT problem

Hello !
I have a problem with my Dreame vacuum robot with Valetudo MQTT connection. It was working ok until now, but in the morning was disconnected and in the MQTT log I can see something like this :

2024-06-04 11:39:12: New client connected from 192.168.178.204:53733 as DVES_1DB972 (p2, c1, k30, u'keops').
2024-06-04 11:39:52: New connection from 172.30.32.2:32810 on port 1883.
2024-06-04 11:39:52: Client <unknown> closed its connection.
2024-06-04 11:41:52: New connection from 172.30.32.2:39032 on port 1883.
2024-06-04 11:41:52: Client <unknown> closed its connection.

The 192.168.178.204 IP is another MQTT device which is working well, but the Valetudo robot is seen as a different IP. Not like my local network. The credentials in MQTT settings of the robot are ok, is connected to WiFi and the web interface is working well. I can fully control the robot from web interface. Just in HA, this morning stopped working. The single change I did, was the position of the robot which is now in living room between 2 TP-Link mesh network adapters. But I don’t think this can affect it, as long as the connection to Wifi is ok, and the web interface is working well.

Thanks !
