Login attempt or request with invalid authentication NGINX Proxy Manager

Hey,

I’m currently using a portmapper from ipv4 port 55652 to ipv6 port 80 and via an proxy the domain to my local hassio instance 192.168.178.2:8123 - I have no SSL cert for that one.

If I want to login on my ha with my phone, there is no problem.
However if I use my notebook I’m getting the message, that I’m unable to connect
And in the home-assistant.log I can see:
WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from a0d7b954-adguard.local.hass.io (172.30.32.1). Requested URL: '/auth/token'. (Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/115.0)

In my configuration.yaml I have 0.0.0.0/0 for trusted_proxies (just for testing ofc)
Adguard is currently disabled.

Do you have any ideas what could be the problem?
