For me this error is raised when I start the streamlit script with --server.headless True But sometimes it runs and gives a very strange message:

  You can now view your Streamlit app in your browser.

Note that I run it as a service so it has never run with a headless=False, so there are no credentials created.

I found that if I add the option --browser.serverAddress "0.0.0.0", it seems to work

Note that I am with

windows 10, running as a service
python 3.7.7
streamlit 0.56

I deploy app in heroku and before this I try run app locally.

$ heroku local

My app starts as expected but I include shell script which must run in server. This script create file ~/.streamlit/config.toml [server] headless = true enableCORS=false port = 5000

After that a had this exception. I had same EXCEPTION! ‘NoneType’ object has no attribute ‘strip’

Yes. I can run app like suggest @hcoohb

$ streamlit hello --browser.serverAddress “0.0.0.0”

But I just remove config.toml 😃
