UI isn't loading

Hi,

It’s been a while since I used Home Assistant. I just updated my dev version, but now when I try to run HA, the console window and the log don’t show any errors, but when I open the UI, the blue bar on top is shown and further the web page just keeps on loading and never finishes.

Any pointers please?

I use this basic configuration now to test whether or not it’s a component issue:

homeassistant:
  name: Home
  latitude: 50.75165412301477
  longitude: 5.132549993324759
  unit_system: metric
  elevation: 73
  time_zone: Europe/Brussels
    
logger:
  default: info

frontend:

I still have the same issue. The log just shows this:

If you DELETE the configuration file (after making a backup) Home assistant will create a basic one that is almost guaranteed to start.

I did that and I still have the same issue :frowning:

Rule out a browser caching issue. CTRL-F5 or similar. I had a case where the HTML was cached and didn’t reflect updates until I did this.

I have this nearly every upgrade. I think my proxy does some clever caching I’m not aware of. If I reboot the Hass host it usually comes back normal.

it wasn’t a caching issue as I had the issue on new browsers as well. I resolved it by reinstalling python
