Hassio 0.52.1 & mqtt with broker : Setup failed for dependencies: mqtt

Hello,

I have just switched from haasbian with 0.49.1 to hassio with 0.52.1 and mqtt is not working with same configuration. (I have 2 boxes, rpi zero with 0.49.1 working, rpi3 with 0.52.1 not working.)

This is the error I have on boot :

2017-08-29 23:08:45 ERROR (MainThread) [homeassistant.setup] Error during setup of component mqtt

2017-08-29 23:08:48 ERROR (MainThread) [homeassistant.setup] Unable to prepare setup for platform device_tracker.owntracks: Could not setup all dependencies.

This is my config, same on both installations :

mqtt:
  broker: m20.cloudmqtt.com
  port: 24410
  username: !secret mqtt_username 
  password: !secret mqtt_password

device_tracker:
  - platform: owntracks
    max_gps_accuracy: 200

and my know_devices.yaml is OK.

Any idea ?

Thanks for your help.

Not sure if you ever figured this out but I get this sometimes too. I also use Cloudmqtt.

I found that if I log into Clouq and restart the service then restart HassIO it works.

It has stopped working since this date, I cannot make it work again even if I try to login to Cloudmqtt. I can see owntrack is posting to correct topic, but HA is not updated.

Note: I have posted an issue on github : https://github.com/home-assistant/home-assistant/issues/9299
