Lost connection between Gladys, MQTT and Zigbee2mqtt

Configuration
1

Hello,

My server just rebooted after a power outage (the storm is coming…).

Unfortunately, the connection between the three components is lost:

Question 1: after reading several posts, I again have a password problem like after the initial installation, but I can’t find the solution anymore:

while MQTT seems to be connected though:

I feel like I’m mixing everything up, is that it?

Thanks in advance

j’ai peur que oui :confused: et j’ai fait le même amalgame à mes débuts sur Gladys.
Si tu as activé z2m et mqtt via gladys en mode « interne », alors z2m a son propre mqtt qui n’est pas celui de l’intégration mqtt, c’est la petite subtilité.
Et comme c’est sur la même machine, mqtt a son user/pwd/port (1883 si je ne me trompe pas) et z2m a son propre user/pwd/port (1884 je crois).
