Troubleshooting Operator Control Panel issues while using the HARMAN browser
Adobe announced the end of development and distribution of Adobe Flash Player by the end of the year 2020. To use the Operator Control Panel (OCP) in the HARMAN browser, you must apply a fix. After applying the fix, sometimes, the action fails and the following error messages may be displayed:

To resolve this issue, delete the cookies, close the browser window, and access the OCP in a new browser window.
