Try turning off the redirect and manage it yourself on the CWP level (with the CSF firewall). I switched my CWP to run an alternate port and only have the HTTPS custom port exposed on the firewall. It will help you avoid getting profiled by someone doing a Shodan search for ports 2030 and 2031, indicators of running CWP and possibly identifying unpatched weaknesses. And since I do the management on my servers solo, I definitely turned off the cPanel wannabe ports 2086,2087. I have left 2083 enabled due to customer familiarity with that port for the customer panel.
