Can not refresh licence

[ephraims]

I cannot refresh my licence. I receive the error message 3cx failed to establish a TCP connection to activation.3cx.com. I am running Professional 16.0.0.1581 and it has expired so it will not let me update. I have been told by my supplier that the licence has been renewed and it is just that it is not hitting the activation server. I can ping activation.3cx.com from the machine. 3cx is running on a windows box and there appears to be no firewall or blocking issues that we can see. How can i get the licence to update/refresh.

The version you are running is quite old and is the reason communication with our activation servers is failing. To successfully establish a connection with our activation server you must be running at least Update 5 of 3CX version 16.

I'll send you a PM with instructions on how to resolve this issue.
