Change ports for product license service

The Product License Service is used by the product nodes to communicate with the License Server. The default port is 59200, but may require configuration if one of the following is true:

• Your firewall blocks port 59200 explicitly or implicitly

• Port 59200 is already in use on your system

The Product License Service port is controlled by the ProductLicenseWindowsService.exe.config file installed as part of the product. The Product License Service must be registered and running on your computer. You can verify this with Windows Task Manager, Services tab.

Port 59200 is the default port that uses WCF communication. However, the Product License Service can also communicate with clients using the gRPC protocol. The Product License Server port for gRPC communication is 59203. Port 59203 is used with version 4.2 or higher of the AVEVA Enterprise Licensing platform.

Change the Product License Service Port

1. On the computer where License Server is installed, use Notepad or another text editor to open the ProductLicenseWindowsService.exe.config or appsettings.json file from the installed location:

   • WCF communication:

     • C:\Program Files(x86)\Common Files\ArchestrA\Licensing Framework\License API2\ProductLicenseWindowsService.exe.config

   • gRPC communication:

     • C:\Program Files\Common Files\ArchestrA\Licensing Framework\License API2\Service\appsettings.json

2. Change the port number as necessary, then save and close the file. See the following illustration for the relevant text to edit.

   Port 59200:

   

   Port 59203:

   

3. Restart the Product License Service.

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