This article provides instructions on how to solve the issue when the fourth step fails with the error message "Failed to upload files to the storage".


Unable to start the exam because the system check has failed. The system has detected that the browser or application has not access to the camera and/or screen recording.

The problem is shown in the screenshot below.


The webcam and desktop cannot be broadcasted by your browser.


  1. Check that your computer meets the minimum technical requirements specified for the exam. Ensure that your hardware, operating system, and browser version are compatible.

  2. Restart your computer. This can help refresh the system and resolve any temporary glitches or conflicts that might be affecting the upload process.

  3. Close any other browser tabs and applications that could potentially access your webcam or screen recording functionality, except for the browser running the exam. These applications can interfere with the broadcast and cause issues with uploading files.

  4. Temporarily disable firewalls and antivirus software on your computer. Sometimes, these security measures can restrict the necessary access and interfere with the upload process. Remember to enable them again after completing the exam.

  5. If you are taking the exam in a classroom or training room environment, consult with your system administrator to determine if certain network security policies are blocking specific ports required for the webcam and screen sharing functionality. Adjustments may need to be made to allow the necessary access.

  6. Try using a different internet connection or a different computer. This can help identify if the issue is specific to your current setup or network environment. Switching to an alternative connection or device may provide a workaround. For example, you can enable the access point mode on your smartphone and connect your computer to it.

Note: After implementing these recommendations, restart your browser: in a new tab enter the address chrome://restart or edge://restart , and press Enter. Then rerun the system check to ensure the changes have taken effect. Verify that the files are now being successfully uploaded to the storage.
