Error 402 ExamBro | How to Fix it

Getting a 402 Error in ExamBro usually means there is a payment or subscription issue with the school’s license, or a communication timeout between your device and the exam server.

Since it’s March 2026 and many schools have moved to the latest encrypted versions of ExamBro, here is how to troubleshoot it:

How to Fix it

1. The Most Likely Cause: School License Expired

In ExamBro’s current architecture, the 402 (Payment Required) status code often triggers if the school’s hosting plan or the specific exam “token” has expired.

• What to do: Ask your proctor or teacher if the exam session is still active. If multiple students have the same error, the school likely needs to renew their server credits.

2. Date and Time Mismatch

ExamBro uses secure handshakes that fail if your device’s clock is even a few minutes off from the server.

• Fix: Go to your device Settings > Date & Time and ensure “Set time automatically” is toggled ON. If it’s already on, toggle it off and back on to force a sync.

3. Clear App Cache (The “Stuck Token” Fix)

If the server thinks you’ve already started the exam but your app crashed, it might throw a 402 when you try to re-enter.

• Android: Go to Settings > Apps > ExamBro > Storage and tap Clear Cache (do NOT tap Clear Data unless told by a teacher, as it might delete your progress).

• Windows/Exambro Browser: Press Ctrl + F5 while on the login screen to force a hard refresh.

4. Network Restrictions

If you are using a VPN or a restricted Wi-Fi (like a coffee shop or a highly secured home network), the app might be unable to reach the “License Verification” server.

• Fix: Disable any VPNs or AdBlockers. If possible, switch from Wi-Fi to a mobile hotspot to see if the error clears.
