Change the default License Server agent port

The License Server Agent Service is one of two Microsoft Windows services used by the License Server. Port 59200 is the default License Server Agent port that uses WCF communication. The License Server Agent can also communicate with clients using the gRPC protocol using port 59201. Port 59201 is used with version 4.2 or higher of the AVEVA Enterprise Licensing platform.

The default port is 59200 / 59201, but may require configuration if one of the following is true:

• Your firewall blocks port 59200 / 59201 explicitly or implicitly

• Port 59200 / 59201is already in use on your system

Port 59200 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 Agent Service default port for WCF communication (59200) is controlled by the LicServer.WindowsService.exe.config file installed as part of License Server. The License Server Agent Service must be registered and running on your computer. You can verify this with Windows Task Manager, Services tab.

The License Server Agent Service port for gRPC communication (59201) is controlled by the appsettings.json file.

Change the License Server Agent Port

1. On the computer where License Server is installed, use Notepad or another text editor to open the LicServer.WindowsService.exe.config (for the WCF port) or the appsettings.json (for the gRPC port) file from the installed location:

   • Port 59200 (WCF communication):

     • C:\Program Files\Common Files\ArchestrA\Licensing Framework\License Server\LicServer.WindowsService.exe.config

   • Port 59201 (gRPC communication):

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

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

   Port 59200:

   

   Port 59201:

   

3. Restart the License Server Agent Service.

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