Hi,
Have you installed both remote desktop session host role and licensing manager role on the same windows 2016 server? Also, are the rds CALs per-user CALs or per-device CALs?
Please make sure you have completed all below actions.
- Remote Desktop Session Host and Remote Desktop Licensing role have been installed.
- Activate the Remote Desktop Services license server

- On the Remote Desktop Session Host server,use group policy to set the Remote Desktop licensing mode (per-user or per-device) and specify the Remote Desktop licensing server.
