I have installed 3CX demo version on my work laptop on a MWare Server instance. I have full internet access but keep failing to register with the license key (Could not connect to license key server - please check internet connection). I have check IE security as I wonder if that could be the issue where sites are being blocked. I have added *://*ecx.com to the permitted sites but wonder if the license is on another site so I am blocking it. Any thoughts anyone ?
