remote login blocked by reverse proxy config

I’ve noticed errors like reported at in my log (though only once when HA starts, not repeating like some report there) and this led me to discover when I click the link that’s supposed to get me to my HA I get 403: Forbidden (which is what I get if I log in from address not listed in http.yaml reverse proxy config), however in log it says the connection was successful.

My own reverse proxy works, I do not really need the link as I do not use it, I subbed for the alexa support and am worried it will affect this.

My http.yaml:

  use_x_forwarded_for: true
  ip_ban_enabled: true
  login_attempts_threshold: 5

So I was wondering if I need to add range for nabu casa as well and if so can you tell me what ip range it uses?

After running into issues running a reverse proxy and nabu casa for Google Home support I figured out the solution to allow both Nabu casa and a reverse proxy. Simply add as a trusted proxy.
