Blackboard: Why Can't I Log in?

System issues: check for Blackboard outages at

Blackboard is available to students who have already registered for at least one course in the current or upcoming term. If you are a student and you have not registered for any classes, then you will not have access to Blackboard.

Are you sure you need Blackboard?

Blackboard is used for course materials, course assessments, and course collaboration.  Common functions that are not in Blackboard:

Common Issues

Most Blackboard login issues are the result of one of the following issues.

1. You're entering the Wrong Username or Password

  1. Clear out any saved usernames and passwords from your browser and enter them fresh
  2. Make sure your CAPS LOCK key is not on
  3. Try logging into Self-Service
    • If you cannot log into Self-Service, then you might be entering the wrong username or password. Try looking up your username and/or resetting your password, then try to log into Blackboard again.
    • If you can log into Self-Service, then you know you are entering the right username and password and there might be another issue. Please read below.

2. Your account is not yet in Blackboard (bad timing)

Did you just register today? Your account will not be added to Blackboard until tomorrow morning - around 4:00 AM. Please try to log in tomorrow - but take note: You won't see your classes yet!

Courses will not become active for students until 4 days before the start date of the course. So check your schedule in Self-Service and note the start date of the course. You will get access to 1st 8-week term courses before you get access to 2nd 8-week term courses.

3. You are no longer enrolled in any active classes

If you have been dropped for non-payment, then your account will no longer be active in Blackboard. Check your schedule in Self-Service to ensure that you are still registered for the current term.

If you are not registered for any current or upcoming courses and the Incompletes Deadline has passed for last term, then your account will no longer be active in Blackboard.

If you are still registered for the current term, please read below.

4. Too Many Session Cookies (HTTP Error 400 Bad Request - Header Field Too Long)

Over time, the session cookies build up until Blackboard throws an error similar to the following:

  • HTTP Status 400 - Bad Request: Request header is too large
  • Bad Request - Header Field Too Long
  • HTTP Error 400. A request header field is too long

To fix this issue, you need to switch to another browser, use Incognito (or Private Window) mode, or delete the cookies for the Blackboard site. Below are links to instructions on how to delete the cookies for a specific website:

  • Chrome (scroll down to "Delete cookies from a site")
  • Edge (scroll down to "Delete cookies from a specific site")
  • Firefox
  • Safari (scroll down to "Remove stored cookies and data")

5. An old session is still active (getting a long error message)

If you are getting a long error code similar to this: 22de52c7-502e-4b42-ad8f-748b241495g1

Click the following link to force old sessions to terminate, then try to log in again:
