Unable to resolve "activate.3cx.com" DNS

[cydigitalnet]

Hello Team!
Kalispera!

Over the last weeks, we are facing a problem with 3CX License Activation.

The message is: "Unable to reach 3CX License Activation Server. Confirm that your Primary DNS Server is able to resolve activate.3cx.com"

The problem is that nothing changed through our computer where 3CX is installed.
Also since the day we faced that, we started having few problems with the phones where we can't hear ourselves each other, also sometimes can't connect to https://fqdn:5001
We can only connect either on localhost:5001 or local-lan-ip:5001.

The problem is that how can I fix it in order to allow this DNS Activation on the computer?
FYI: the computer is on Windows 10, all port forwards on CYTA Modem are Activated as well as on Windows 10 Firewall.

Thank you
