How to solve a problem 

It means that the problematic node could not resolve activation service. 

1. Check an access to activation services from the problematic node
   curl -v https://activation-v2.kaspersky.com/ --cacert activation-v2.kaspersky.crt
2. And if there is no success connection, open an access to
   https://activation-v2.kaspersky.com
   https://activation-v2.kaspersky.com/ActivationService/ActivationService.svc
3. And check a page with configuring network access - https://support.kaspersky.com/KWTS/6.1/en-US/189764.htm
