My configuration

Home Assistant core server as 192.168.1.43:8123
Debian  running Nginx  192.168.1.42 (force SSL)
Nginx has home.mydomain.net  internally pointing towards 192.168.1.43

Nginx is configured to allow me to access https://home.mydomain.net  pointing towards  static public ip  directly. 

step 2. enable http integration forward


Reference - HTTP - Home Assistant

The following is all I needed to do, and a reboot of course.

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 192.168.1.42

otherwise，you will get error
Recently I have been getting these 400 bad requests when trying internally or externally from WAN.
