Since FLS is a Java-based application, you have Java 8 bundled to the application. FLS doesn't support Java 9 and later versions.

FLS is a Java-based application and requires Java 8 or earlier versions. FLS doesn't support Java 9 and later versions. To check the version of Java you have installed, run the following command:

java -version

Network requirements

The fully qualified name of the FLS host should be resolvable to its IP address. To verify this, run the following command on the FLS host machine:

ping $(hostname -f)
ipconfig /all

And then ping the obtained hostname:

ping <hostname>

During installation, the MSI distribution creates the JetBrainsLS user. To let FLS get license data from JetBrains Account, allow incoming and outgoing connections for this user.

Make sure that the environment where FLS will be located, has established connection to the following resources:

Traffic between FLS and JetBrains should be passed as is, including original certificate data for HTTPS connections.

Product being registered with FLS should have access to FLS network.

Communication with JetBrains Account

FLS contacts JetBrains Account hourly to:

  • Obtain license information about the number and type of licenses available for distribution in the organization.

  • Send statistics of license usage to build usage reports in your JetBrains Account (the number of available and allocated licenses by a product).

If FLS has not contacted JetBrains Account within 2 hours, the FLS administrators will receive a "License Server Connectivity Problem" email informing them about the issue. JetBrains can't detect what exactly happened on FLS, so the email contains just a simplified warning.
