Connection error Connection failed with status 0.

Deployment

hi. I wrote a small application on streamlit. Everything works locally on my machine. When I fill in my code and run it and go to the web interface streamlit connects to the server and crashes with an error:
“Connection error Connection failed with status 0.”
has anyone encountered such a problem?

Hey @Ilya_Sergeev,

Can you share a link to your deployed app and GitHub repo so we can try to reproduce this issue?

I have the same problem, but for me it intermittently happens when I leave the app open and inactive for long time (over night for example). I get this same error and the app stops working (need to refresh)… not a major,but annoying user experience.
My app is deployed in Azure as AppService.

We had the same problem with an internal deployment and cleaning the browser data (Edge browser: history-> clear browsing data), we fixed the problem.

“Connection error. Connection failed with status 0” with our Streamlit app running on a iPhone. We get this error message about 10 seconds after putting the device into Airplane mode. When the device is subsequently taken out of airplane mode the error message is automatically dismissed. Streamlit 1.37.1 running on Github Codespaces and same behaviour at Render.
