COLRS has recently received several reports of students experiencing issues when attempting to take a Canvas quiz using Respondus LockDown Browser. Recent security updates on Mac and Windows may be the cause of most common issues with LockDown Browser, and are explained in greater detail below:

When LockDown Browser starts, it must be permitted to access this server: static-public-downloads-cloud.respondus.com

LockDown Browser accesses this server in order to check if an update has been issued by Respondus. If your computer and/or network is blocking access to this server, the LockDown Browser session will not be permitted to continue.

It’s possible that your computer’s security settings are blocking access, or you possibly have a firewall or anti-virus software running on your computer or network that is causing the block.

When this issue occurs, students may encounter Error Code a4 or the following warning: “Update server is not supplying information, or the connection to update server is blocked.” Information on how students can resolve this issue can be found in the Respondus Knowledgebase for Mac users and Windows users. Please share these resources with your students if you receive any reports of issues.

If students are experiencing other problems while using Respondus, such as the lack of the required webcam, Information Technology Services may be able to help by allowing students to borrow hardware. Students should contact ITS Client Services at 217-206-6000 or techsupport@uis.edu for more information on this program and hardware availability.
