HA automations working in background but can't connect to frontend in browser "Unable to connect to Home Assistant"

Installation
1

Running HA in a docker container on an Ubuntu server laptop.

Everything was working ok but yesterday the laptop ran out of hard disk space and various services like mosquitto and zigbee2mqtt started throwing up a bunch of errors. Not sure if that’s related but that’s the only thing out of the ordinary.

I’ve tried setting up HA from scratch (docker stop, rm, pull, run) but I still get the same error message:

image

None of my auth credentials or API password have been changed.

From my home-assistant.log:

Same here, however, I get a continual "Loading data … " message.

Running Hassio

Would like to downgrade, so, how does one accomplish that?

3

Try clearing your browser’s cache, or using incognito/private mode in the browser.

4

Doesn’t work unfortunately, and I get the same error on my desktop and mobile.

5

Another line that comes up in my HA log:

ERROR (MainThread) [homeassistant.core] Error doing job: Fatal error on transport TCPTransport (error status in uv_stream_t.read callback)
TimeoutError: [Errno 110] Connection timed out
6

I have met the same question. Is your problem solved ?

7

Somehow your .storage/auth file got corrupt, please follow the guide to rebuild your user system, see https://www.home-assistant.io/docs/authentication/#lost-owner-password

8

I actually just ended up hosing the whole system and rebuilding from scratch so I can’t test it out, but thanks for the tip! I’ll know what to do next time :slight_smile:

I had the same issue – couldn’t access frontend after a rollback – and this solution worked for me. Thanks!

Brand new installation:
haos_rpi3-64-7.1.img.xz
http://192.168.1.72:4357/ able to access and shows
|Supervisor:|Connected|
|Supported:|Supported|
|Healthy:|Healthy|

http://192.168.1.72:8123/
connection refused.

same setup:
haos_rpi3-7.1.img.xz used the 32 version
no problem able to access http://192.168.1.72:8123/

what could be wrong?
