Modify Browser Internet Security Settings
Internet Explorer removes necessary cookies when its security settings are set too high. When this occurs, users who access the Electronic Prior Authorization window might see unauthorized responses, even when they have used a valid, active authorization token. For example, the system might automatically log you out.
If you encounter such situations, modify the Internet Explorer security settings. These steps cover Internet Explorer 11. Settings for other browsers may differ. Refer to the appropriate documentation for other browsers for similar settings.
