HTTP integration is not set-up for reverse proxies

Third party integrations

I’m setting up Traefik v2 as a reverse proxy on my home network. I have several services within and outside the docker instance of Traefik 2 working well as subdomains. When trying to get HA to work, I get the error

ERROR (MainThread) [homeassistant.components.http.forwarded] A request from a reverse proxy was received from 192.168.86.6, but your HTTP integration is not set-up for reverse proxies

I had this before when setting up remote home assistant from HACS, and already have the below in my configuration.yaml. I added the .6 address (static IP of the reverse proxy) as well, but still no dice.

Here’s my http config snippet:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 192.168.86.6
    - 192.168.86.0/24
    - 127.0.0.1
    - ::1

And my app-hagarden.toml for traefik 2 (domain changed to example.com).

[http.routers]
  [http.routers.garden-rtr]
      entryPoints = ["https"]
      rule = "Host(`garden.example.com`)"
      service = "garden-svc"
      middlewares = ["chain-noauth"]
      [http.routers.garden-rtr.tls]
        certResolver = "dns-cloudflare"

[http.services]
  [http.services.garden-svc]
    [http.services.garden-svc.loadBalancer]
      passHostHeader = true
      [[http.services.garden-svc.loadBalancer.servers]]
        url = "http://192.168.86.42:8123" # or whatever your external host's IP:port is

Any ideas?

ETA: Here’s the error if I update to https://192.168.86.42:8123

Was setting up the proxy on instance A and changing configs on instance B.

I’ve got both hooked up now.
