Auto login via trusted_users

i have tried a lot, searched the dark net and the bright net … but no solution so far - what is wrong with my setup?

192.168.2.123 being the IP of the tablet.
192.168.2.10 is HA

I have a ngix reverse proxy active, but even when I disable ngix, the auto login does not work.
