IBKR Server Version Issue?

[Chloboe]

Hi all,
I'm trying to log into my IBKR paper trading account using the example script (https://github.com/nautechsystems/nautilus_trader/blob/develop/examples/live/interactive_brokers/historical_download.py), and I believe I've correctly configured IB Gateway. However, I keep encountering this error message:

2025-03-20T00:46:20.015348000Z [INFO] TRADER-000.InteractiveBrokersClient-000: Connecting to 127.0.0.1:4002 with client id: 0

Does anyone know how to fix this? I'd really appreciate any insight anyone might be able to share. Thanks!

make sure to use correct IB_ACCOUNT(DUE123213 find it in settings title of tws/gateway).

e.g.

exec_clients={
            "IB": InteractiveBrokersExecClientConfig(
                ibg_host="127.0.0.1",
                ibg_port=IBGATEWAY_PORT,
                ibg_client_id=1,
                account_id=IB_ACCOUNT,  # This must match with the IB Gateway/TWS node is connecting to
                instrument_provider=instrument_provider,
                routing=RoutingConfig(
                    default=True,
                ),
            ),
        },
