Find Your Problem & Fix

Problem 1: “Access Blocked” on School Networks

When a school network or Google Workspace administrator policy blocks Blooket, students and teachers see an “Access Blocked” screen.

Quick fix: Select “Request Access” on the screen, then notify your Google Workspace Administrator. They need to approve Blooket access through the Google Admin Console.

Problem 2: Can’t Log In, Join a Game, or Host a Game

The most common cause is a Chrome extension (like an ad blocker) interfering with Blooket’s site functionality. While Blooket doesn’t run ads, these extensions can still block parts of the site.

1. Try first: Open Blooket in Incognito/Private mode (disables all extensions). If it works in Incognito, an extension is the culprit.
2. Second cause: firebaseio.com may be blocked on your school network. Blooket uses this domain to host and join games; if it’s blocked, games can’t be hosted or joined. Note: This does NOT affect your ability to log in.
3. Third cause: Usernames are case-sensitive. If logging in with a username, use the exact capitalization you used when you registered.

Problem 3: Connection Issues and Slow Performance

Before trying any fix, use Blooket’s official diagnostic tool: debug.blooket.com. This tool tests all critical Blooket services and shows exactly which ones are failing, giving you (or your IT department) a precise list of what needs to be addressed.

If school networks block Firebase or SSL traffic inspection, this can slow or break game data. The fix is asking IT to whitelist .blooket.com.

Problem 4: Images and Blooks Not Showing Up

This is almost always a school network issue. The network is blocking the two services that deliver Blooket’s images:

• res.cloudinary.com: primary image hosting.
• images.unsplash.com: secondary image hosting.

Fix: Ask your IT administrator or network manager to unblock both domains.

Problem 5: Student Account Creation Notification Appearing

After finishing a game, students see a prompt asking them to create a Blooket account. Some teachers don’t want this shown.

Fix: Before your next game, on the Host Settings page (after selecting a game mode), uncheck the option that says “Allow Student Accounts.”

Frequently Asked Questions

What’s the single fastest way to rule out a Chrome extension as the cause of a problem?

Open Blooket in Incognito or Private mode. This disables all extensions automatically, so if the problem disappears there, an extension is confirmed as the cause.

Does a firebaseio.com block affect logging in?

No. It specifically affects joining or hosting games, not the login process itself. If you can log in but can’t join or host, this is the most likely cause.

Who should I contact to unblock a domain on a school network?

Your school’s IT administrator or network manager. They can whitelist the specific domains (firebaseio.com, res.cloudinary.com, images.unsplash.com, or .blooket.com) depending on the exact problem.

What does Blooket’s diagnostic tool actually check?

debug.blooket.com tests all of Blooket’s critical services and reports exactly which ones are failing, giving you or your IT department a precise, actionable list instead of guessing.

Can a student accidentally cause the “Access Blocked” screen?

No. This is a network or Google Workspace administrator policy blocking Blooket at the infrastructure level, not something caused by an individual student or teacher account.

Is the missing-images problem something I can fix myself?

Usually not directly. Since it’s caused by network-level domain blocking, you’ll typically need to ask an IT administrator to unblock the specific image-delivery domains.

What information should I include when contacting Blooket support?

Email from the address associated with your Blooket account for the fastest resolution, and describe the specific symptom (what’s happening, when it started, and any error messages).
