Hi there,

It looks like the request that you are making is timing out. Can you share the code snippet that you are using for this specific request?

Besides, as a general suggestion, in case that you are connecting to a database, make sure that the database cluster is accessible from the server that you are running your Flask application on:

Best,

Bobby
