Home Assistant

Reverse proxy

The proxy to Home Assistant must have WebSocket support enabled.

Without proper configuration, Home Assistant will reject requests coming from a proxy with 400: Bad Request. If the proxy server is a Docker container (e.g. Nginx Proxy Manager), the trusted proxy must be the IP address assigned to the container by Docker. Add the following to configuration.yml:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - XXX.XXX.XXX.XXX # Docker IP of proxy server
