netbox via nginx proxy manager: Bad Request (400)

[Runningman-work]

Hello,

I am using latest netbox with latest nginx poxy manager.

ALLOWED_HOSTS is set to the FQDN pointing to my nginx proxy manager. In npm I'm connecting to netbox via docker app name ("netbox-app") and port 8080.

I always get Bad Request (400), even though I put the FQDN of the service in the ALLOWED_HOSTS variable. By setting DEBUG=true I get the error DisallowedHost and the info to set my host name to the FQDN. doesn't work, does anyone have an idea?

Even the following is set for nginx Proxy manager in the Advanced section:

proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

regards,
Stefan
