@gabe_maldonado’s hash issue and @svilupp’s TypeError indeed look like https://github.com/streamlit/streamlit/issues/242 26 . So those should be fixed soon!
As for the @gabe_maldonado’s issue with port 80, I’m not so sure what’s happening. We fixed a bug related to port 80 a few point-versions ago. So perhaps you’re not running the latest Streamlit? Can you please double-check the version you have?
$ streamlit version

Should be 0.47.4
