App with SF connection suddenly failing


I have an app deployed in the cloud with a connection to Snowflake that is giving me this error since this morning:

This connection is in OCSP Fail Open Mode.

After that, I get messages:
The service has encountered an error while checking the health of the Streamlit app: Get “http://localhost:8501/healthz”: read tcp> read: connection reset by peer


Streamlit server consistently failed status checks

Everything was working fine yesterday evening, but suddenly this morning it is not. I have made no changes and I have checked that the issue is not related to snowflake credentials, and I am able to run the connection from any local jupyter notebook.

What could be causing the issue?

Can you share the link to the deployed app?
