Brute force is an attack (hacking) method that involves using an automated system to guess the password to your web server or services. cPHulk is a WHM feature that helps protect your web server from malicious users who try to gain unauthorized access through brute force attacks.
The IP Address details in cPHulk are maintained in the form of a MySQL database. In case you are locked out of your server due to cPHulk, you need to follow the below process to regain server access.
To Regain Server Access / Locked Out due to cPHulk
Login to your VPS through SSH.
Stop the MySQL service using the command:
service mysql stop
Go to https://<Your_VPS_IP_Address>:2087 and try logging in.
Now, go to Home -> Security Center -> cPHulk Brute Force Protection and delist/whitelist your local system's IP Address.
Start the MySQL service using the command:
service mysql start
