OSError: write error

Hello,

I don't see any issue with my application side but still getting this OSError: write error. The error goes away after sometime. I'm not sure what is causing this problem. Could you please help us troubleshoot this issue.

That happens when a client disconnects before the response has been fully sent to the client. It could be because the timeout on a client is too small, or that your site is slow and a user disconnects before the response is received.

Can you assist me in pinpointing the root cause of the issue, whether it lies within the application code, server configuration, network conditions, or client behavior?

It's either in application code or client behaviour and we cannot help you to work out which - that is something that you have to do. See https://help.pythonanywhere.com/pages/MySiteIsSlow/ for checking your application code.
