WP Lockout: Incident ID

A user attempts to log in Chrome again a few minutes after closing a private browser session. Gets:

This page can’t be displayed – your request has been denied for security reasons.
The incident ID is: xxxxxxxxxxxxxxx

Looks as if it is an Apache code which increments in every such occurrence of an incident. Should it be publicly shown in open posts, and is it filtered through to or handled by Cleantalk in anyway? Couldn’t find anything close to it in the security logs other than a “banned” login from a user with a similar user name.

He is able to login again later on the mobile, we suspect it’s an issue with his IP address.

Thanks.
