hello.
I'm using WHMCS and have DirectAdmin server.
I created server and configure in WHMCS but it created fail!!

Connect to server I use SSL and other port (don't default port of DirectAdmin) for secure, How to config it???

WHMCS doesn't support in other ports than default port(in this case 2222) and this file is encoded so you can't add this custom port support.

Unfortunately, there is no actually realistic solution.
(there is option to build this module from zero by your self / wait until WHMCS will support in custom port)

If you submit a ticket to WHMCS support they MAY create a custom module, or just modify one that will allow you to use your own port

Thank you for your replys. I will contact to WHMCS for customize module :)
