What can cause problems with sockets on Bitrix?

Question

1C-Bitrix

For the first time, I decided to pull the layout on Bitrix and saw problems with sockets in the errors. What could be causing this problem and how can I solve it?

Answer 1

When checking the site for errors using Bitrix, the site makes a connection to itself. If the site is closed with a password or through the admin panel in the main module, then the check will fail - sockets.

Answer 2

The problem may occur for various reasons. See the error logs for details.
But in most cases, explicitly specifying the domain or site ip in the /etc/hosts file helps.
You need to add to the existing line:
