Issue: Unable to obtain a license for playback from Swank DRM license server. Please note, this information is intended only for license servers hosted at Swank, not the Cached License Server.
Cause: In certain environments, it is common to have strict network rules that can interfere with normal network traffic. In order for the cloud streaming licensing service to function properly, a number of network endpoints must be reachable.
Resolution:
Consistent Errors: If the error is consistent, this is a good indication the license endpoint is being blocked. The licensing endpoints listed below must be reachable by the playback device. This information should be brought to the attention of your institution's network administrators as well as the administrators for any managed devices (such as Chromebooks).
License server communication can be confirmed by attempting to reach the URL below for the appropriate DRM used in your playback environment.

Intermittent Errors: If this is occurring intermittently, it may not be an outright network ban or block. Instead, these kinds of errors can sometimes be caused by something more subtle such as SSL Inspection rules or rules governing JavaScript behavior.
In some cases, the error may be presented after successfully playing for a period of time. If the device is struggling to download content chunks (several seconds at the lowest bitrate 400kbps), this can eventually lead to a timeout and cause a licensing error when the device attempts to reconnect to play the content.
If you're using Wi-Fi, try switching to a wired network and see if you get similar results.
