I was forwarding 443 to 8123 directly. I was in effect bypassing NGINX. Of course, I had to forward 443 to 443, then NGINX forwards 443 to 8123. So simple and obvious…

Same error happens when I use a Long-Lived Access Token to send a POST to /api/alexa/smart_home via public URL or internal IP of my Home Assistant instance running 2023.1.7:

I suspect the error is related to configuration in http: and those in Settings -> System -> Network -> Home Assistant URL

My set up ingress is proxied through Cloudflared:

http:
  ip_ban_enabled: true
  login_attempts_threshold: 3
  use_x_forwarded_for: true
  trusted_proxies:
    #home

    - 197.234.240.0/22
    - 198.41.128.0/17

Home Assistant URL has the public facing Cloudflare hosted https URL in Internet field, with the internal IP:8123 in the Local Network.

Same error over here, but mine started showing after I added SSL via the Nginx Proxy Manager.

Saw this as i wanted to figure out if it is possible two serve up both http and https via NPM (which is not easily possible, at least not to my knownledge). I would suspect the configuration.yaml has no ssl_key/ssl_certificate entry or you transport a http to the home assistant instance which expects https (signified by the key) and therfor confusing aiohttp. (https has to be forced by npm)
