Configure offline license key validation​

If you need the Pdftools OCR Service to operate without a direct internet connection to verify the license key, set up the Licensing Gateway Service (LGS).

With the LGS, you can configure the Pdftools OCR Service to:

  • Use a partially offline mode called connected mode. For more information, review Connected mode.
  • Use full offline mode. For more information, review Full offline mode.

Configuration in connected mode and full offline mode​

Prerequisites​

To let the Pdftools OCR Service operate without a continuous internet connection, install and configure the LGS. Review Connected mode, or Full offline mode for specific guidance.

Procedure​

After configuring the LGS with the Pdftools OCR Service using the connected mode or full offline mode, follow these steps:

  1. Find your worker node’s appsettings.json. The following is the default path of the worker configuration file: 
    C:\Program Files\Pdftools\Pdftools OCR Service\PdftoolsOcrWorker\appsettings.json
  2. Edit the LgsURL parameter value to point to the machine where you configured the LGS. The default value is: 
    "LgsURL": "http://localhost:9999"

For more information, review Default appsettings.json in the Pdftools OCR Service documentation.
