Hi, I followed the fastapi traefik tutorial from here: https://traefik.io/resources/traefik-fastapi-kuberrnetes-ai-ml/, so I have the exact same config as in here Deploying FastAPI (and other) apps with HTTPS powered by Traefik - DEV Community
Everything works fine for the http part of the api, I have https.
But i'm also using python-socketio, and when i try to connect to the websocket endpoint, the https request get through, but I then get a 403 error instead of having the websocket upgrade.
I tried adding this label:
traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto=https to my fastapi service, it doesn't work.
I get the error:
Firefox can’t establish a connection to the server at wss://...
Any idea how I can fix this ? Thank you
