This is a generic error that can be caused by any number of issues, all dependent on where you are and what you are doing.
Most typically when taking a course over the internet it is caused when a page, image, or file is trying to load but the connection between the user end and the server that the course is hosted on has temporarily lost connection or is being blocked.
- The first trouble shooting step is to refresh the browser or log off the website and log back on to re-establish the connection.
- If this does not fix the issue it may be necessary to clear out your browser's cache and cookies or for less work you can try switching to a different internet browser.
- If the problem still persists you will need to contact RedVector Client Support for further assistance.
