Troubleshooting problems with software licensing


This document helps you resolve subscription or fixed license issues, or you can submit a support ticket.

Determining the licensing method in use

First, determine the software licensing method on your Access Server so you can follow the correct procedure for activation and troubleshooting. Your Access Server uses one of the following:

  • Fixed license key: purchased for one-five years, starting from ten connections.
  • AWS tiered instance: only available on Amazon AWS, in sizes five, ten, 25, 50, 100, 250, and 500.
  • Unlicensed: limited to two connections.

Refer to the following sections for the specifics of each licensing method.
