Long time cpanel user here who has recently been testing out Virtualmin. So far I love how smooth and fast everything is running. I am having an issues getting any billing panel to connect to it though to create accounts. Initially I was trying it with WHMCS and the connection kept timing out. I then tried Boxbilling, which just flat out said could not connect to the server. Since according to the forums for those billing panels, they are both working correctly with Virtualmin, I believe something may be misconfigured within Virtualmin. I can't find any settings related to the Remote API though.
Is there something that has to be enabled somewhere to allow these type of API calls? I am able to connect in a web browser to domain.com:10000/virtual-server/remote.cgi
I am currently using Virtualmin GPL during my testing phase.
