WebSocket w/ Python API Not Opening/Streaming?

I’m using the code available from a tutorial at https://github.com/hackingthemarkets/alpaca-market-data-streaming-api but I can only see that the connection was closed and I can’t see that it was ever opened or that anything was streamed. Using the command line with direct json works for me but it doesn’t work for me with Python for some reason. Anyone have any guesses why? For context, when I run the exact code with my API keys in the config file, I only see the “closed connection” statement printed and nothing else happens.
