Configuring the License Server Core Service Port

The License Server Core Service is one of two Microsoft Windows services used by the License Server. The default port is 55559, but may require configuration if one of the following is true:

• Your firewall blocks port 55559 explicitly or implicitly

• Port 55559 is already in use on your system

Port 55559 is one of a range of ports used as temporary, local "scratch" ports when Internet clients, such as web browsers, email, and browser-based applications such as AVEVA Enterprise License Manager and License Server connect to the service ports of remote Internet servers.

The License Server Core Service port is controlled by the local-configuration.yaml file installed as part of License Server. The License Server Core Service must be registered and running on your computer. You can verify this with Windows Task Manager, Services tab.

Change the License Server Core Service port

1. On the computer where License Server is installed, use a file editor such as Notepad or any commercially available XML editor to open local-configuration.yaml from the installed location:

   C:\Program Files\Common Files\ArchestrA\Licensing Framework\License Server\Server\local-configuration.yaml

2. Update the HTTPS listening port with the desired port number.

   

   Note: If you are using the legacy port 55555, then you have to change the port number in the # HTTP listening port section which appears in the beginning of the file.

3. Restart the License Server Core Service.

4. Open the new port in your firewall.

   You might need to consult your company Information Technology department for enterprise firewall configuration.

   For how-to information, see Open a port in your firewall.

5. Open the product Configurator and provide the configured port number. For how-to information, see Configure Enterprise Licensing.
