If you as a student or instructor encounter an issue with the Google Drive LTI presenting you with an “Access Denied” or “Authorization Failed” message, try the troubleshooting steps below.

These scenarios may be encountered when an instructor embeds a Google Drive file into an Assignment or a student submits a Google Drive file and the instructor cannot access it in Speedgrader. The causes could be that an instructor or student are logged into Google Chrome with multiple accounts (confusing the system) or there’s a network privacy blocker (blocking the ability to authorize).

If Signed Into Google Chrome With Multiple Accounts

  1. Sign out of all Google accounts in Chrome and then re-authenticate with only your Boise State account.

  2. Clear browser cache and cookies.

  3. Verify the browser is not blocking third-party cookies.

  4. Delete the Google Drive LTI token and Google Drive Registered Services and re-authenticate.

    1. In Canvas navigate to Account > Settings

    2. Scroll down to the Registered Services section

    3. If present, delete Google Drive by clicking the red X

    4. Scroll down to the Approved Integration section

    5. Delete Google Drive LTI by clicking the trashcan icon

    6. Sign back into Google Drive Registered Services

    7. Navigate back to the Assignment, Speedgrader, etc and re-authenticate Google Drive (this should create a new Google Drive LTI token in Account Settings)

If Signed Into Google Chrome With Multiple Accounts, and, if the above steps did not resolve the issue

  1. Log out of Canvas.

  2. Navigate to https://myaccount.google.com/permissions.

  3. Under Third-Party apps & services with account access click on Google Drive LTI by Canvas.

  4. Click the Remove Access button.

  5. Sign out of Google.

  6. Repeat steps 1-5 for each Google account logged into Chrome. Not all accounts will have Google Drive LTI by Canvas listed under Third-Party apps with account access, but it is important to remove access for those accounts that do.

  7. Close all your browser windows and relaunch Chrome.

  8. Log back into Google with your Boise State credentials.

  9. Log back into Canvas.

  10. Navigate to the Assignment or Speedgrader and re-authenticate Google Drive.
