Why is Blooket Not Working | Most Common Reason

Based on current reports, Blooket appears to be operational for most users, so the issue is likely specific to your device, internet connection, or school network.

Here is a checklist to figure out why it isn’t working for you and how to fix it:

1. Are you on a School Network? (Most Common Reason)

If you are at school, the network firewall has likely blocked Blooket or a background service it needs to run.

• The “Firebase” Issue: Blooket uses a service called firebaseio.com to run live games. Even if the main Blooket website loads, the game will fail if the school blocks this specific service.

• The Fix: You cannot fix this yourself. You would need to ask a teacher or IT administrator to “whitelist” firebaseio.com.

• Workaround: Try using a personal mobile hotspot or your phone’s data plan (if allowed) to see if it loads there.

2. Check Your Browser Extensions

Ad blockers and privacy extensions often break Blooket because they mistakenly think the game code is an ad or tracker.

• The Fix: Temporarily disable your ad blocker (e.g., uBlock Origin, AdBlock Plus) or run Blooket in an Incognito/Private window to see if it works.

3. “No Healthy Upstream” Error

If you see a white screen with the text “no healthy upstream”, this means Blooket’s servers are temporarily overloaded or having trouble talking to your specific connection.

• The Fix: Wait 5–10 minutes and refresh. This is usually a temporary glitch on their end that resolves quickly.

4. Clear Cache & Cookies

Sometimes your browser holds onto an old, broken version of the site.

• The Fix:

  • Chromebook/Chrome: Press Ctrl + Shift + Backspace > Select “Cached images and files” > Click “Clear data.”

  • Refresh the Blooket page.

5. Quick Status Check

If none of the above works, double-check that a widespread outage hasn’t just started:

• Check Downdetector or search Twitter/X for “Blooket down” to see if others are reporting the same issue in the last few minutes.
