The version 9 licensing process is based upon an "always connected" pattern.
The licence verification process
Once a day, the encoder will check in with the Central Licensing Server (CLS).
The encoder itself does not access CLS - all requests go via the server.
The CLS will then check the current licence for any updates (including changes in expiry date, or revocation) and send the results back to the encoder.

Ways this can fail
This can fail by either:
If the encoder loses its connection to the EdgeVis Server.
The EdgeVis Server is unable to communicate with the central licensing portal.
When this happens
When an encoder licence update fails, it will continue to retry for up to 10 days.
At this point, it continues to fail; the encoder will enter into a grace period, which the interface will notify you of.
During this grace period, the encoder will continue to function normally, but the system will notify users of this issue.
Upon the expiry of this grace period (30 days), the encoder will cease normal operation - which is already impaired do to the lack of server connection.
How to fix this
To fix this, simply resolve the connection issue and reconnect the encoder to your server.
The encoder will then request an update of its licence and resume working normally.
