The first thing to try is rebooting your app. If that doesn’t work, I’d recommend deleting and re-deploying. @Yusof I rebooted your app and it seems to be working now.
Hi everyone,
I’m sorry but i have the same issue.
What is the good way to solve this problem please?
Thx

I’m having the same issue today. I updated and rebooted but hangs processing app…
Same here! Seeing this issue today.
I’m guessing any reboot causes this error as my other apps are working fine as cached in their servers. Would be nice to be notified of such matters as it causes users to think twice on their code compatibility with wasted time.
Hello,
I started to use Streamlit today (06 Feb 2023) and I wanted to start with a very minimal example program.
Just printing a line of text on the screen.
but: the deployment gets stuck in “please wait” and “Spinning up manager process”.
It is such a simple program (only 5 lines of code) and it does not work. That is sad.

Same here, stuck on “Spinning up manager process”
Same issue since today.
Same issue, I’ve been stuck for the last few hours.
Hi! Could you try to delete and recreate the app? If the issue persists, could you provide a link to the app and a screenshot?
