Diagnose & Fix Plesk Outage

Job ID: 40568711

Budget: $30 – $60 USD

My AlmaLinux 8.10 server is running Plesk, Juggernaut Firewall, Apache, PHP-FPM, MariaDB and sits behind Cloudflare. After a recent DDoS wave I tightened the Juggernaut Firewall rules following AI-generated advice and, ever since, the main website only returns blank pages while every other hosted or backup domain works fine. Web pages are the only service failing; mail and databases stay responsive.

I already restarted services and even rebooted the node, yet the symptom persists. I need an expert who routinely works with Plesk and Juggernaut Firewall to:

• Dive into Apache, PHP-FPM and MariaDB logs to pinpoint the root cause of the blank-page delivery.
• Audit the latest Juggernaut Firewall changes I applied and reverse or fine-tune anything that is blocking legitimate web traffic.
• Restore normal page loading without touching the functioning addon domains.
• Document exactly what went wrong and give me step-by-step hardening guidance so I can fend off future DDoS spikes without taking the main site offline again.

Need to check the mail server too for outgoing message to pass the tests

SSH and Plesk access will be provided immediately. Please outline your troubleshooting plan, estimated time to resolution, and any similar cases you have solved.
