Materia: 404 Error Message

Summary

Correcting Materia 404 Error Message

Body

Overview

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.

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:
