Are you seeing the following message?
When signing into Blackboard, some users report getting an authentication expired error message (see picture below). The error prevents users from logging into the Blackboard system. Even when the user clicks “Return to Login Page” and attempts to sign in again, the error reappears.
How to fix it
Once this error occurs, the only way to resolve it is to clear your browser’s cache and cookies (see "Clearing Browser Cache and Cookies" section below). Please follow those steps.
To prevent this error from occurring in the future, it is essential that you always log out and click "End SSO session" when you are finished using Blackboard (see picture below).
To logout, click the logout button in the upper right corner of Blackboard.
On the next screen, click the “End SSO Session” button. Do not leave Blackboard logged in on your computer when you are not using it.
