Hi I am getting this error when i check the licence,

3CX failed to establish a TCP connection to activation.3cx.com.
Ensure that the local or border firewalls are configured to allow outbound traffic to activation.3cx.com

I have checked in the forum and it says set the DNS to 8.8.8.8. I have set the primary dns to 8.8.8.8 and restarted the server and still the same error.

Need some help urgently.

I am getting these errors

License limit is reached.
