The three most common reasons for receiving a Banner 9 Authentication Error are:
- Exiting the Banner 9 application by hitting the back arrow and then attempting to login to Banner 9 without closing and reopening browser
- Your session timing out after 2 hours of inactivity and then attempting to login to Banner 9 without closing and reopening browser
- Using a desktop shortcut or browser bookmark created by either dragging the URL to the desktop or bookmarking the Banner 9 application from the browser
Clearing the browser's cache and cookies, or retyping the URL ( https://appnav.athens.edu ) should help resolve the issue.
