Streamlit stuck on loading screen on Docker

See original GitHub issue

Summary

When attempting to run streamlit under Docker it is stuck on the “connecting” screen.

Steps to reproduce

docker run -it --rm -p 42851:8501 python:3.7 /bin/bash
pip install streamlit
streamlit hello
Go to http://< server IP >:42851/
Streamlit is stuck “connecting” The issue also appears when using a Dockerfile

Expected behavior:

Streamlit should finish “connecting” and start the hello app

Actual behavior:

The application is stuck on “connecting” screen (checked for over 1h before giving up): Output from the terminal:

root@35427972d7ee:/# streamlit hello

  Telemetry: As an open source project, we collect usage statistics.
  We cannot see and do not store information contained in Streamlit apps.

  If you'd like to opt out, add the following to ~/.streamlit/config.toml,
  creating that file if necessary:

    [browser]
    gatherUsageStats = false


  You can now view your Streamlit app in your browser.

  Network URL: http://172.17.0.6:8501
  External URL: http://<external server IP>:8501

Is this a regression?

Python version: Python 3.7.5 (same behaviour on python 3.8 and latest anaconda)

I have a similar issue when requesting the page through the domain name instead of the ip of the server. Could they be related?

@MarcSkovMadsen I have configured the ~/.streamlit/credentials.toml file as you described, unfortunately the issue still persists, though I tried your docker image and it worked correctly which suggests that it is some sort of configuration issue.
