Realtime example broken?

[mariosk8s]

I'm trying to run the real time example on Debian 11 with Python 3.9 and keep getting a 404

/usr/bin/python3.9 /nas/projects/electronic/mybus/tibber/tibtest.py

Process finished with exit code 1

It doesn't matter whether i use my own access token or the demo one.
This happens on 26.13 and also on main 28.2 with the following patch to make it jibe on python 3.9

`diff --git a/tibber/realtime.py b/tibber/realtime.py

• def sub_endpoint(self) -> str | None:

• def sub_endpoint(self) -> Union[str, None]:
  """Get subscription endpoint."""
  return self._sub_endpoint
  `

I would try to debug this myself, but am getting utterly lost in the async world.

The URL in init is wrong. It should be wss://websocket-api.tibber.com/v1-beta/gql/subscriptions
(or rather, it should be acquired by asking for websocketSubscriptionUrl.

Yes, i neglected to mention it, but i adjusted the URL in 28.2 to no avail.
