Thanks Jay. Although I just opened a ticket about this, let me ask you some more details. You opened port 8443 for incoming, outbound or both connections? Also, you opened those ports on the server that WHMCS is hosted? Or on another server that WHMCS connects to create hosting packages? (this is what I am trying to do). Thank you, Dimitris

How did you solve this issue? I have the same problem (using the trial version). I suppose it is the firewall that blocks WHMCS, but which port should I open? Thank you Dimitris
