Canvas Quiz Not Loading or Submitting? 10 Fixes

Canvas quiz stuck loading, not submitting or showing an error? Ten practical fixes for browsers, connections, LockDown Browser and what to do if time is running out.

A Canvas quiz that will not load or submit is stressful, especially with a timer running. Here are ten fixes, from most to least likely to help.

1. Check availability

If the quiz is not yet available or already closed, it will not open. Check the "Available from" and "Until" dates on the quiz page.

2. Check requirements

The quiz may need an access code from your teacher, a specific network (IP filter), or Respondus LockDown Browser. Read the message on the quiz page. See LockDown Browser for Canvas.

3. Use a supported browser

Use an up-to-date version of Chrome, Firefox, Edge or Safari. Very old browsers may not load quizzes correctly.

4. Disable extensions or use a private window

Some extensions, such as ad blockers or script blockers, can interfere with Canvas. Try a private window, where most extensions are off, or temporarily disable them.

5. Allow third-party content for New Quizzes

New Quizzes runs inside an embedded frame. Strict privacy settings that block third-party cookies can stop it from loading. If New Quizzes shows a blank area, allow cookies for your Canvas domain or try another browser.

6. Clear cache and cookies

A corrupted cache can cause loading loops. Clear your browser's cache for the Canvas site, then log in again.

7. Check your connection

Switch from Wi-Fi to a wired connection or a phone hotspot. Unstable connections cause failed saves and submissions.

8. Do not open the quiz in several tabs

Having the same quiz open twice can cause conflicts and odd log entries. Use one tab only.

9. Try the Canvas Student app

If your browser fails and the quiz does not require LockDown Browser, the Canvas Student app may work as a backup. Check with your teacher first.

10. Document and contact your teacher

If nothing works, take screenshots or phone photos of the error with the time visible, and email your teacher through Canvas Inbox or school email straight away. Clear evidence makes it easy for them to reopen the quiz or give extra time.

Prevent problems next time

  • Start quizzes early, not at the deadline.
  • Test your setup on a practice quiz.
  • Keep your laptop charged and plugged in.

Frequently asked questions

Why is my Canvas quiz not loading?

Common causes are browser issues, extensions, an unstable connection, a quiz that is not yet available, or a requirement like LockDown Browser or an access code.

What should I do if my Canvas quiz won't submit?

Check your connection, do not close the tab, try submitting again, and if it keeps failing, take screenshots with the time visible and contact your teacher immediately.

Does the timer stop if the quiz won't load?

No. Once started, the timer keeps running. Report the problem quickly so your teacher can help.
