You may see the following error or a similar error while trying to play a Kaltura video or access other content embedded in your Canvas course site:

It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application. To resolve the issue, please update your settings to allow 3rd party cookies.

Allowing third-party cookies is necessary for the proper functionality of many external tool integrations in Canvas. These cookies contain necessary information that the external tools in Canvas use to verify your identity and your right to access the content. Some examples of external tool integrations in Canvas that need to set third-party cookies in order to function properly are Kaltura (My Media) videos, Collaborations, and PlayPosit. If third-party cookies are being blocked by browser security settings, these integrations will show an error message that references cookies or local storage. Sometimes, instead of displaying an error message, an external tool won't finish loading or won't load at all if its cookies are being blocked. Internet browser developers have begun blocking third-party cookies in their default security or privacy settings to protect users from being tracked by third-party advertisers and marketers that place ads on other websites. Unfortunately, these settings often block content within Canvas courses, which commonly incorporate content from legitimate third-party applications. This guide details how to set Google Chrome up to allow third-party cookies for all websites. For enhanced security and privacy, this guide also provides instructions on how to allow specific cookies on a website instead of allowing blanket access to all third-party cookies.

UW-Green Bay recommends students use Google Chrome as their internet browser while accessing their Canvas courses as Chrome is the most widely supported browser by Canvas and its integrated tools. Google Chrome can be freely downloaded from Google's Chrome website. Installing and using Chrome on your computer will help ensure you experience the greatest compatibility with the tools deployed in Canvas. We also recommend turning off any third-party ad-blocking or security-oriented Chrome extensions while accessing Canvas, as these extensions can override your browser's built-in cookie settings and interfere with the functionality of external tool integrations.

Instructions for enabling third-party cookies in other mainstream internet browsers and mobile browsers are linked to at the end of this document.

To temporarily allow all third-party cookies in Canvas on Chrome

The following steps allow you to quickly allow all third-party cookies in Canvas or another website; however, this setting can only be enabled temporarily and will be reset by Chrome every 90 days.

1. Navigate to the Canvas page that contains the third-party tool that is experiencing blocked cookie issues.
2. Near the right-end of Chrome's address bar, select the eye icon.
3. Enable the "Third Party Cookies" option slider
   
   
   
   
4. The page should refresh automatically and the necessary cookies will be allowed for 90 days. After 90 days, Chrome will revert to blocking third-party cookies on that website and you would need to repeat these steps.
