Hello, good evening I just recently installed WHMCS, I cant use WHMCS connect, every time I select server to log on to it says connection refused. I have the latest cPanel Latest WHMCS Server properly configured (able to log on to WHM if I go to servers section.) Tried with Firewall off I used to be able to use it in the past, not now. Any help much appreciated.
