Materia: 404 Error Message


Correcting Materia 404 Error Message



Remember to always access Materia from within a Canvas course by following the instructions on the Materia support page. Note that launching Materia in this manner opens a new browser tab. It is possible to have multiple Materia tabs open at once but keep in mind that your session will eventually time out. If this happens, you will need to close all open Materia tabs, return to your Canvas course, and launch Materia from the course again. If you continue to experience an issue connecting to Materia, exit your browser completely and try again; or consider trying another browser.


If you attempt to access Materia from Canvas and receive a "404" error message, and you have followed the steps above, your browser may be set to block third-party tracking. This blocking is enabled by default on both Safari and Firefox, but third-party tracking must be allowed because it permits the Canvas and Materia servers to talk to one another. To resolve this:


  1. In Safari, go to Safari Preferences.
  2. On the Privacy tab, uncheck the option to& Prevent cross-site tracking.


  1. Go to Firefox Preferences / Settings.
  2. On the Privacy & Security tab, adjust the& Enhanced Tracking Protection section to the Custom setting and change the Cookies setting to Cross-site tracking cookies.
    NOTE: The default setting isolates other types of cross-site cookies, which prevents Canvas from launching Materia successfully.


  1. Go to Settings.
  2. On the Cookies and Site Permissions tab, select Manage and delete cookies and site data.
  3. In the options that appear, uncheck the Block third-party cookies setting.


  1. Go to Settings.
  2. On the Privacy and security tab, select Third-party cookies.
  3. Set the default behavior to either Allow third-party cookies or to Block third-party cookies in Incognito mode, depending on your preferences. Do not select Block third-party cookies.
