The error 'blocked by CORS policy' occurs when attempting to view videos in Google Drive in Chrome, preventing users from accessing video content. This issue affects individuals using Chrome on their Macs and may be related to recent updates or changes in the browser's settings.

This frustrating error can cause inconvenience for users who rely on Chrome to access their work videos. In this troubleshooting guide, we will walk through the steps to resolve the 'blocked by CORS policy' error in Google Drive using Chrome.

🛑 Root Causes of the Error

  • The primary reason for this error is due to the implementation of Cross-Origin Resource Sharing (CORS) policies in Google Drive. When a user attempts to access a video in Google Drive, the browser sends an HTTP request to the server to retrieve the content. However, if the server does not include the correct headers in its response, the browser will block the request due to security concerns.
  • Another possible cause is related to the use of proxy servers or VPNs that may be configured to bypass CORS policies. In some cases, this can lead to the 'blocked by CORS policy' error when accessing Google Drive videos.
