"Login attempt or request with invalid authentication" when trying to access remotely

Hello,
I need your support. I have the same issue with my Android App creating these error logs all days and meanwhile my mobile was pushed to the blocking list so i had to delete this again. The issue is only showing up with my LAN IP adress.
My problem is, i’m using “NGINX Home Assistant SSL proxy” to configure NGINUX as i was following below guide to setup remote access:

But here i do not have any location configuration to setup. Can you help me, what i have to add exactly where to get the issue been resolved?
Thanks for your help.
