Since yesterday basicly, my HA doesn’t work remotely anymore.
Yesterday I swiched over from an old YAML maintained Lovelace to a webbased/maintained frontend.
My Home assistant runs on a Yellow, My Traefik proxy runs on my NAS.
When I connect locally to http://yellow-ip:8123, everything works fine, but when I go to https://my.external.url and login, I get the message: “unable to connect” with the countdown counter.
When I look in my traefik logs, I see a lot of error 500 from HA for RequestPath /api/websocket:

My rules file for traefik is as followed:
http:
routers:
homeassistant-tls:
tls:
certresolver: certresolver
entryPoints:
- external-https
service: homeassistant
rule: Host(`my.external.url`)
services:
homeassistant:
loadBalancer:
servers:
- url: "http://yellow-ip:8123"
I have added my proxy to the trusted_proxies in my configuration.yaml
In the browser console I only see the error "WebSocket connection to ‘wss://my.external.url/api/websocket’ failed: "
I’m a bit puzzled here. Perhaps it is the translation that Traefik does from wss to http? I can’t find anything online regarding (Traefik) reverse-proxies and websocket access for Home-Assistant. I there anyone here that has an idea?
