OK I was able to make it work by disabling CORS in setup.sh :
echo "\
[server]\n\
headless = true\n\
port = $PORT\n\
enableCORS = false\n\
\n\
" > ~/.streamlit/config.toml

Awesome! I didnāt have time to try the new version since I originally posted but thatās good to know.
@Julien_Almarcha and @Alexandre_Domingues: Please note that since 0.48 these config options can now be specified directly on the command line e.g.:
streamlit run --server.enableCORS false my_script.py
Yay!
Thx, good to know!
Please guys, could you give some tips to publish a simple script in python using heroku ?
A tutorial ?
Have a look at this gist:
all you need are 3 files:
I see most of the comments are from 2019, but if anyone trying to deploy on Heroku today make sure your requirements.txt file has streamlit version code. If not specified it keeps showing āConnecting to streamlitā when viewed through the link. Maybe a bug in the latest version.
requirements.txt
streamlit==0.49.0
setup.sh
mkdir -p ~/.streamlit/
echo "
[server]\n
headless = true\n
enableCORS=false\n
port = $PORT\n
\n
" > ~/.streamlit/config.toml
3.Procfile
web: sh setup.sh && streamlit run your_app.py
This worked like charm.
Works perfectly thankyou for this

@Nikhil_Agarwal , kindly help to me solve the above issue as you mentioned followed same steps but giving same application error.
Please follow this ( ignore the Docker portion). It will work as Iāve tested it
Hello! I am using streamlit==0.67.1, and I keep seeing this error message 'āConnection failed with status 0.ā. Even when running āstreamlit helloā I see this error. Iām not sure how to troubleshoot this, could someone assist? Iām using a virtual machine and I wasnāt seeing this error 3 weeks ago, but it has been happening for 2 weeks now.
@anasalu I had the same problem. Try Nikhilās solution above with the Streamlit version set to 0.49.0 and edit the setup.sh file to exlude any new line characters (\n). Also, if you copy the code, be sure that the quotation characters an non-directional (should be the default of your keyboard, so you might just have to retype those). If this doesnāt work, try including a runtime.txt file in your directory specifying the version of Python. My Streamlit app is working with python-3.7.5 in my runtime.txt file.
Hi @cgusb, welcome to the Streamlit community!
While an okay thing to do for troubleshooting, thereās no reason why downgrading to 20 versions of Streamlit ago should be necessary to deploy apps on Heroku. Plenty of people on the forum are able to deploy with current versions of Streamlit. Like you also say, the issue is usually around newline or other characters that mess up the deployment process.
Best,
Randy
I created this project some time ago, it guides you on how to deploy Streamlit on Heroku and optionally add a Nginx proxy to allow for simple authentication.
Hi Randy, youāre absolutely right. I upgraded back to the current version (Streamlit 0.67.1) and my app deployed successfully. Thank you for pointing that out! I should have tried to update again once I got things working.
I have compiled some resources to deploy streamlit to heroku (its without the nginx proxy though)
Hi everyone,
I am trying to deploy my app on Heroku but I am unable to figure it out.
Can anyone pls resolve.
Here is the logs:

Have you looked at the several tips in this thread? And this guide?
Also post your Procfile
and setup.sh
please?
