MQTT Boot Loop Issue - cant find discovery.json

[Craer (paul newell)]

Was gone a few days, came back and my install was no longer working (couldn’t reach gui). After some research on here, the issue looks like it’s the same as what happened about a year ago with MQTT. One of the last things I did was to enable MQTT.

Now i’m in a boot loop, and having the same issue as here: Tried to make a copy of SD card and now can't connect to HA - #9 by keithco

It looks like the fix was to login with root and gain access to host OS (with a # prompt), I have successfully gotten here. I then use “docker ps” and can see that supervisor is restarting every 20 seconds or so. I then went to try and delete discovery.json in /mnt/data/supervisor, however it is not located anywhere that I can find.

Everything seems to match up to this being the same issue, however I cant seem to make anymore headway. Any recommendations would be great.

This is the thread I was using for research:

Mosquito MQTT update v3 broke my hassio

If you are running HassOS you can connect a keyboard and monitor to the pi (if that’s what you are using). Then you use “root” to get to the Hassio CLI. From there you use “login” to get to the host OS (with a # prompt). Then you can use docker ps to see what is going on with your containers. If supervisor seems to be restarting within a short amount of time repeatedly, you can remove discovery.json which is in /mnt/data/supervisor. Then reboot the whole thing and see what happens.

I too have lost connection to my MQTT room sensors since updating to 0.99.3.
After resetting the ESP32 board they will connect for a short while then disconnect.
AsusWRT is also complaining and now have no presence detection since this update.
