I have a user 'mqtt-user' set up in HA. Those credentials set in the 'MQTT' service. I am seeing 7 devices in the MQTT service.
When I go to configure in the service and try to listen to an event I cant get it to "Start listening". It just reloads the page quickly and nothing's working. According to ChatGPT it means it cant connect to the broker, but I have followed all the steps multiple times now. I am stuck..
