A high number of incoming requests originate from one or more unique IP
addresses. This could indicate a bot attack. The following guide shows how to
check for and block suspicious IP addresses.

bndiagnostic was not useful. Could you please tell us why?

Generalized Nature of Recommendations: The tool provides high-level recommendations, but the issue might require detailed analysis of your specific server setup, application configuration, or traffic patterns.

Describe your issue as much as you can

Primary Problem:
PHP-FPM fails to start, causing Apache to be unable to serve PHP-based applications. Errors in the Apache logs suggest a failure to connect to the www.sock socket or backend.
Detailed Observations:
Apache logs show repeated connection errors to PHP-FPM.
PHP-FPM logs are not included in the diagnostic bundle but might contain additional details.
OPcache was configured but could be affecting performance or stability due to incorrect settings.
High incoming traffic might be contributing to server overload.
Additional Context:
The issue might stem from a misconfiguration of www.conf or php.ini that impacts PHP-FPM's ability to start properly. This would cascade into Apache being unable to process requests.
