I have a WHMCS install on a host that does not allow outgoing connections to port 8083. I have confirmed the API works and the host is allowed API access via verifying all of the commands work on a different machine. I am hesitant to change the port of the panel to anything nonstandard, and was wondering if there is any way to make the API listen on a different port-- say 443 with a specific hostname.
Has anyone else encountered a similar problem? Is there anything I can do to try and get the connection working? Thank you for your help!
