Streamlit working on web browser (not mobile)

Hello everyone!

Amazing tool! Love what you guys did.

After building and deploying my app to I came to notice that it doesn’t open on mobile browsers (specifically IPhone when using Safari and Chrome) : when you hit the link, you’re faced with a blank page (not even an error message)

Could this be related to Heroku?

It’s hard to debug on mobile. On desktop, everything works fine. Has anyone faced this issue?

Thanks for your help.

Hello @ahmedbesbes, welcome to the community! And what a nice app you have delpoyed there :slight_smile:

On my side your link works perfectly on iPhone Chrome and Safari though, I’ve been able to change dataset and play with the sidebar parameters. Did you change anything in between?


Great app!

Hello @ahmedbesbes ,

I had the same issue. My app worked on web browser, on some mobiles but not on all mobiles.
I solved that by taking a previous version of Streamlit (0.74.0 in my case).

Hope it will help you.

Hi All,

Even my application was not launching on iPhone earlier then I tried with Streamlit (0.74.0), it worked for few days and it’s not working again.

Application loads on iPhone and it gives me Connection error - connection timed out.
