ERROR: License Number is NOT Valid

Applies to Standalone CAS Operation ONLY.

Problem:

During an upgrade or installation of your STANDALONE CAS, you may see this error:

Checking license online...
License number xxxxxxxxxxxxxxxx is NOT valid or internet connection is not working.

This issue may arise when your system’s root certificates expire. You’ll have to update your Ubuntu to refresh the certificates.

NOTE: You should update your system routinely. Security vulnerabilities are patched in these updates, and allowing them to persist may be a costly oversight.


Solution:

  1. Update your Linux distribution.

    1 sudo apt update && sudo apt dist-upgrade
  2. Reboot your server.

  3. Try the CAS install/update again.
