Hello,

usually there are different reasons why this happen:

- license is invalid
- license is expired already
- license is exceeded (too many devices)
- the activationserver of Kaspersky is not reachable due to geoblocking or other Firewall / Proxy settings.
The address is activation-v2.kaspersky.com with Port 443
You will find addresses and services and ports needed for Kaspersky Security Center here:
