Looking for how to connect to a Demeter remote instance

I was trying to figure out if ogmios-python is the correct tool for my need, but didn’t want to setup everything yet just to try it. So I’ve an instance on Demeter, and was hoping to connect to it.

Currently my connection code is the following:

    with ogmios.Client(
        host="mainnet-v6.ogmios-m1.demeter.run",
        additional_headers={"dmtr-api-key": "ogmios...mykey"},
        secure=True,
    ) as client:
        ...

But it’s erroring with a timeout at the inner sock.connect(sa) step. If I’m adding http_only, I get a NotImplementedError.

Is it just me doing something wrong? Is there a correct way to connect to Demeter?
