EOF error when post request flask app

I’m building a flask app and I have a table with many users. I can select as many users as I want and make a POST request… the problem seems to be that the request size is too big for the server configuration cause the app doesn’t recieve all the inputs and displays EOF. I’ve done this locally and it works fine. Thanks for the support!


We often see an “EOF” response from Flask/Gunicron apps relating to a Gunicorn timeout. If the request takes longer than the set Gunicorn timeout, an empty response is passed, which manifests as just “EOF”.

You’re likely to see some logs like:


You’ll need to investigate why your requests take so long, and/or adjust your Gunicorn timeout settings.
