D2L Brightspace - Why the LockDown Browser Dashboard is Not Opening for One Course

If the LockDown Browser Dashboard is successfully loading for many courses, but failing for one, the following are possible causes: 

1. There may be an empty or corrupted value in the default "Submissions" message. Here is a KB article that deals with a related symptom of this:

2. The Self-assessments or Survey tools are disabled in the specific course. These are required (along with the relevant instructor permissions for them) for the Dashboard to open. To check on this, go to Course Admin > Tools and make sure both of these tools have a check mark showing they are enabled.

3. One or more of the quizzes has an IP restriction.  The D2L SOAP API which the Dashboard uses does not permit this. You'll need to remove the IP restriction from all quizzes in the course before the Dashboard will successfully load.  

Note: if the IP Restriction icon remains on the quiz (even after you've deleted the restriction from the quiz's "restrictions" tab) the Dashboard may still fail to load. If this occurs, a workaround is to delete the quizzes with the restriction, then create new ones. Otherwise, you will have to contact D2L to remove the icon.

4. The Instructor has invalid role permissions. Please refer to the LockDown Browser Administrator Guide, under the section "Instructor Roles and Permissions for IMS Configuration."

5. Invalid or special characters in quiz titles (such as colon, hash, ampersand, etc.)
