ESPHome Add-on UI not available - 502: Bad Gateway

Hi there, I just got my ESP32 and wanted to get going but am allready failing at starting ESPHome on HA.

I installed the latest version 2024.3.1 and restarted HA. After that I tried to start add on but and in the beginning it always showed me that its not ready yet and asked me to retry. Confirmed a couple of times but did not change anything. After another restart and some more waiting it seemed to have started but I keep getting

502: Bad Gateway

and again the ask to try again.

I dont know if there are special logs for add ons but in the normal logs I could find:

Anyone an idea what Im doing wrong or could do to resolve?

EDIT:
Now I found the logs:

I would try in the first instance to uninstall the addon, and install it again.
