Error after deploying to share.streamlit.io

Hey guys,

this is the first time using streamlit for me so I dont know if this an error on my side or a serverside issue.

After I Deploy the App I can use it for a short amount of time. After that it stops Working with the following messages appearing in the console:

[manager] Streamlit server consistently failed status checks [manager] Please fix the errors, push an update to the git repo, or reboot the app.

The memory usage on my local machine is about 150mb. I dont know if thats a problem.

In case its helpful:
Streamlit
Github repo

Looks like everytime I reboot the app, I can use the app once until it stopps working. Probably a memory issue since it is still running fine on my local machineā€¦ I hope you guys can help me.
