Oh no. Error running app. App down since Jan 23th

Community Cloud

My Streamlit app has been down since January 23rd.

This is what my Streamlit interface displays. I have already clicked “Reboot” multiple times, but the error persists.

My Environment & Error:

  • Python Version: 3.13

  • Streamlit Error Message: “Oh no. Error running app. If you need help, try the Streamlit docs and forums.”

  • Issue: I cannot see any logs in the Streamlit admin panel.

Any suggestions?

Hey there, thanks for reaching out and sorry you’re running into this! The “Oh no. Error running app” message on Streamlit Community Cloud often means your app has hit resource limits (CPU, memory, or storage), or there’s a compatibility issue with your Python or package versions. Since you’re using Python 3.13, note that not all packages (including some Streamlit dependencies) may be fully compatible with this version yet, which can cause silent failures and prevent logs from appearing. Rebooting alone won’t fix version incompatibilities or resource overages.

Here’s what you can try:

  1. Downgrade your Python version to 3.12 or 3.11 in your app settings (Streamlit Community Cloud does not use runtime.txt; set the version in the UI).
  2. Check your requirements.txt for any incompatible or missing dependencies, and pin your Streamlit version (e.g., streamlit==1.37.0).
  3. If your app uses large models or datasets, optimize memory usage or move data loading to a database, and use st.cache_data or st.cache_resource to reduce resource consumption.
  4. If you still can’t access logs, try deleting and redeploying the app, as sometimes a fresh deployment can resolve stuck states.

For more details, see the official docs on resource limits, upgrading/downgrading Streamlit and Python versions, and deployment troubleshooting. If you’re still stuck, please share your requirements.txt and a minimal reproducible example so the community can help debug further!
