I am having an issue with bridge

Q: I am having an issue with bridge

./bridge.sh Connected to substrate at: ws://127.0.0.1:9944
bridge() exited with result: Err(HyperError(hyper::Error(Connect, ConnectError("tcp connect error", Os { code: 111, kind: ConnectionRefused, message: "Connection refused" }))))

what could be wrong?

A:

Look like the TEE client is not running. Please make sure ./app is running.
