Error in websocket [Error: Server sent no subprotocol

[lijju-matt-root]

I am trying to connect to existing JupyterHub Server(on EMR master node) from my local computer(Mac) and and running into below issue. The JupyterHub UI opens fine on the local computer and able to access, but connecting to it from VSCode is getting the error. Have set up the certs as well.
