Unresolved address

Issue

Unresolved address error on license server start

* FAILED org.eclipse.jetty.server.Server@7a9a042:
                    java.net.SocketException: Unresolved address
                    Caused by: java.nio.channels.UnresolvedAddressException

Solution

Make sure that a configured, fully qualified hostname is resolvable to your IP address as described in Server URL.

Address is already in use

Issue

* FAILED ServerConnector@2bdd8798{HTTP/1.1}{0.0.0.0:8080}:
                java.net.BindException: Address already in use

Check if there is other software running on the same host and port and stop the software to make the host and port available for usage by FLS. If it is not possible re-configure FLS to use another port as described in Server URL.

Issue

                ServerConnector@2243bc0d{HTTP/1.1}{notexistinghost.jetbrains.com:8080}:
                java.net.BindException: Cannot assign requested address

Solution

Make sure that the host/port you configured exists and its address is available.

This error may also occur when the host you configured server doesn't match FQDN or IP of the machine where it is installed.

Check the host name.

hostname -f

Compare obtained host name with the host specified in the configuration file (placed in the installation directory):

./conf/service-config.properties

If they don't match, adjust configuration so that they do.

Windows service failed to start

Issue

FLS failed to start or stopped right after start when FLS is launched as Windows service

Solution

Make sure that the software is allowed to read/write from/to:

%userprofile%\\.jb-license-server sub-directory in user directory
<fls_home> directory
%programData%\\JetBrains\LicenseService directory on the machine with FLS is installed where %programData%\ is a path to an application data directory

In case of MSI distribution software is running by the service user JetBrainsLS.

Change to the FLS installation directory using the command line.
Stop FLS using the following command:
./bin/license-server.sh stop
./bin/license-server.sh java set <path to JRE home directory>
Start FLS using the following command:
./bin/license-server.sh start
