To maintain a secure testing environment, learning institutions use a LockDown Browser that they must install on each student’s computer. It is a modified version of Google Chrome that blocks accessibility.

It’s a software used by educational institutions to prevent cheating during online exams. A specialized web browser prevents students from accessing other websites or applications during an exam.

When an exam is launched, the LockDown Browser checks for updates from the server. If an update is available, it will download and install the update before proceeding with the exam.

If the server is unavailable when it attempts to check for updates, it will display the error message – LockDown Browser update server is not supplying update information – due to security threats.

It is crucial to keep LockDown up to date to maintain the security of online exams. If you have difficulty updating the browser, you can take a few steps.

Why can’t I use the LockDown Browser?

A particular-purpose web browser locks down the testing environment within a learning management system.

It prevents cheating by disallowing other applications, printing, copying, going to different URLs, or accessing other browser tabs during an assessment.

This helps ensure that students can only focus on the test material and not get distracted by other things.

If you are trying to use LockDown and it is not working, there are a few possible reasons why:

• LockDown Browser may not be compatible with your computer’s operating system. Check the system requirements to ensure that your computer meets the minimum requirements for using it.
• It may be incompatible with your web browser. If you are using a browser other than Edge, you will need to install the Firefox Add-on to use LockDown.
• You may not have permission to install software on your computer. If you are using a school or work computer, you may need to get permission from an administrator before you can install LockDown Browser.
• Your antivirus software may be blocking LockDown Browser from being installed. Try temporarily disabling your antivirus software and then installing it again.

Finally, this could be because the site is down or undergoing maintenance or because your institution has not yet upgraded to the latest version of the browser. 

Either way, you will need to contact your institution’s IT department for further assistance. 

For a student, this could mean that you will not be able to take your online exam. In this case, you should contact your instructor as soon as possible.

If you are a teacher, this could mean that your students will not be able to take their online exams. In this case, you should contact your institution’s IT department for further assistance.
