I am experiencing an issue with my cPanel/WHM server after adding another IP address to the cPHulk Brute Force Protection Blacklist.

Issue Details:

• After adding the IP to the cPHulk blacklist, I can no longer access WHM (port 2087) or cPanel (port 2083).
• The issue affects both my own IP address and other users' IP addresses.
• The web server is still running normally, and all hosted websites remain accessible.
• Only the WHM/cPanel management ports (2087, 2083, and related services) are inaccessible.

  Hey there!  Are you able to access the server over the command line?  If so, you could disable the cPHulk service so you can revert those changes:
