I installed whm on a centos server, but there was some problem with the network and the installation failed. Now with that fixed I reinstalled, and now ports 2082 and 2086 arent working to get into cpanel and whm, but the default page is showing up on port 80 properly. What should I be checking?
Maybe the cPanel/WHM didn't install properly, make sure that your VPS is connected in a stable state from the network. You can install cPanel directly without any other configuration via SSH.
