ESET Server Security connects to the ESET License server a few times per hour to preform checks. The Interval check parameter is set to Automatic by default. If you want to decrease network traffic caused by licensing checks, change the Interval check to Limited and the licensing check will be done only once a day (also after server restart).

With the Interval check set to Limited, all license-related changes done to your ESET Server Security via ESET Business Account and ESET MSP Administrator may take up to one day to apply.
