Traefik 2.5 websocket proxy (nomad)

Traefik Traefik v2
1

Hi,

I spent two last days fighting with websockets and traefik. Is there anyone who use websockets and traefik as a proxy? My configuration is as follows:

# traefik proxy (only relevant part of proxy)
entryPoints:
  http:
    address: ":80"
    http:
      redirections:
        entryPoint:
          to: https
          scheme: https
          #permanent: true
    forwardedHeaders:
      insecure: true

  https:
    address: ":443"
    forwardedHeaders:
      insecure: true


tls:
  options:
    default:
      minVersion: VersionTLS12


...

And my job deployment labels are:

            "public",
            "traefik.enable=true",
            "traefik.http.routers.${NOMAD_JOB_NAME}-http.rule=Host(`${var.fqdn}`)",
            "traefik.http.routers.${NOMAD_JOB_NAME}-http.tls=true",
            "traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto=https,wss"

In devtools I see only connection failed errors.

I have it deployed via nomad and traefik uses consul as a provider. Everything works fine, when I use directly port exposed by nomad websocket works.
