• This error usually appears when no (or incorrect) username or password is specified in admin area for a customer in WHMCS. Username and password should be the same that customer uses to login to his cPanel account.
• Another possible reason is a firewall on cPanel server that blocks connections of WHMCS server on port 2083 (even if WHMCS and cPanel is one server). To fix this problem, whitelist IP of WHMCS on cPanel.

Please log in to some WHMCS client, open details of some hosting service and you will see this button in the right side menu box.
