Python, socket error processing request?

Question

Python

Good afternoon, I'm studying python, I raised the site on the hosting, but it started to give an error that I can't make out. What could be the problem?

2015-11-02 21:57:44 +0000] [31789] [ERROR] Socket error processing request.

Answer 1

The error logging system in django is configured to send messages by mail. And the smtp mail server is apparently set incorrectly.
An error occurs somewhere in the django core while processing the request. The text of this error could tell us something. But when trying to log this message, an attempt is made to send it by mail and an attempt to connect to the mail server (which either does not exist or is not a mail server) while waiting for the connection, crashes with a timeout Connection timed out.
Check your django config, are there any addresses like example.com?
