Hi there, totally new with 3CX and in this forum. I am trying to make fresh installation of 3cx v12 on a windows 2012 server VM on esxi Host. When i try to activate i get a warning message: Could not contact License Key Server. Please check your internet connection on the computer running 3cx phone System. If you are using an http proxy server, you need to configure proxy settings from Control Panel > Internet Options > Connections. I managed to install it and activate it on Windows 7 but i want it on 2012. I have access to internet, i can telnet on 443 on 188.8.131.52 which this seems to be the IP of the license key server judging from my firewall logs. Can you please advice?
