Private openhab cloud right configuration for

I succesfully configured openhab private cloud with last version of the openhab-cloud connector on ngnix following the directions, but I cannot make working,ngnix is configured on 2 apps, webapp 3001 and main on 3000, and there are 2 process of node, thanks for @Wolfgang_S for the configuration here

This is my configuration on my vps server (8.6 KB)
but when clicking to it ask me for user and password, does anyone know the correct configuration?
I added as you can see in the attached file:

add_header Set-Cookie X-OPENHAB-AUTH-HEADER=1;

but may be is misplaced?
