Problem with connecting to WHMCS?

[ByteCube]

Hi there,

I have a server with OVH that is running Proxmox 4.1.

I have purchased a WHMCS plugin so that they can communicate, in order to have things like automatic provisioning and allowing customers to re-install OS and such. I have tried three different modules (little out of pocket now due to my frustration haha), and all fail to login to the server. I have tried multiple things, which I will attempt to list below:

• Adjusting IPTables on the Proxmox server in order to accept all connections
• Disabled Firewall on Proxmox server
• Opened the port for Proxmox (already opened, confirmed this through an online port-checker service)
• Reset the password for the account root to something simple, same issue
• Set up a new user and tried logging into that, same error
• Disabling all kinds of firewalls/iptables on the proxmox server.
• Pinging both the Proxmox server and my website, all of which seems OK.
• Checking ports open on WHMCS server(more info below)

I have also tried other stuff like SSL/Non-SSL and nothing seems to make a difference. The port is 8006, the default port. It's like something is blocking the connection entirely from reaching the Proxmox server.

My WHMCS install is hosted by GoDaddy, but I have looked in various places and I can't seem to find anywhere in the settings that could be blocking the connection (No firewall, no IP blacklisting, etc). Does anyone have any ideas? It definitely ISN'T the user/password combo. I have confirmed this login numerous times, typed it manually, etc etc etc. I am also using the PAM login, although I have tried the other one but to no avail.

Any help is greatly appreciated.

Why don´t you just ask the vendor of these commercial modules for help? Better than here.

These are third party modules and therefore we do not know why these modules does not work or how they have to be configured to work.
