This is active, I can see the gui, its just not populated with data, even though I have at least two devices working via MQTT
Perhaps try to clear your cache? (ctrl-f5).
good thought, but didnt work
What browser?
Just to eliminate browser issues - try
- incognito window
- a different browser
- a different computer and/or OS if you have such things.
I had added a username and password for Z2M to auth against Mosquitto (added the same user and pass in Mosquitto) but just noticed the system has changed it to user: addons with a pass. I added that same user and pass (addons) to the MQTT server but no luck.
I also noticed I dont actually have an “addons” user under people/users. Is this an issue?
/config/zigbee2mqtt/configuration.yaml
homeassistant: true
mqtt:
server: mqtt://core-mosquitto:1883
user: addons
password: aifaaqu0einahS5oPothxxxxxxxio6UKiephaileeN8oixxxxxxphah
serial:
port: tcp://192.168.10.85:20108
adapter: deconz
frontend:
port: 8099
devices:
'0x3425b4fffea07b36':
friendly_name: '0x3425b4fffea07b36'
'0x9035eafffe1a1de3':
friendly_name: '0x9035eafffe1a1de3'
The best way to use the mqtt addon is to create a user and password for HA in here 
and then use that user and password in whatever is trying to connect to mqtt.
Just tried linux - Brave, chromium, firefox including incognito windows on two different Linux machines + Edge on a virt windows machine and they are all the same … not showing anything populated in the GUI.
I added a specific user to the users area and added it to Z2M but it didnt work. I checked my HA log and found this, which led me to find my root dir is full. Just dealing with that now and will report back. With a bit of luck, this will be the solution. Thank you both for your help so far.

ConnectionResetError: Cannot write to closing transport
That would stuff things up!
ok, so after much googling, the previous error is not related to disk space but rather something else that everyone seems to ignore. The /dev/root issue of 100% is also not an issue as its not actually a disk that we need to worry about.
I have made some progress in that I have a Nabu Casa account and if I use that URL in the browser rather than 192.168 etc, the web gui works.
If someone can explain why it works on the NC url and not on the local one, I would be grateful.
TIA
I can definitely see devices in the dashboard using either my internal or external URL.
I did this from the GUI and rebooted, still no luck 
I am sure it is going to be something simple, will persevere until I find the cause. Let me know if you have any other ideas.
Are your settings in the GUI or yaml?
Just tried the internal and external URL settings in YAML and no difference.
I was having this problem and all I needed to do was to reconfigure the MQTT integration, I added the HA user/pw that I defined for the MQTT broker and voilà, the devices started appearing. The user was set as homeassistant and some random pw. Don’t really know why, mb default?
I have the same issue. All devices are running correctly but I can not see any device in the zigbee2mqtt ui…
I have tried all the mentioned things without success… I have also no errors on the logs and addon logs…
Fixed:
Recover a backup. I think the configuration file of zigbee2mqtt was broken. How ever?
