Addon error code 502: Bad Gateway

Hi guys. I installed the addon Advanced SSH & Web Terminal on my Home Assistant OS and when I try to go to the web interface of that addon it says 502: bad gateway.
Can anyone help me? Hope you reply!

I get same error. HomeAssistan versiyon 2023.9
Advanced SSH & Web Terminal version: 15.0.7

Same error running HA OS 10.5 Code 2023.9.2… I uninstalled and installed SSH. add-on which works fine

Is there another “ssh” add-on? I only see the Advanced SSH & Web Terminal add-on.
