Registering Miscorsoft AI Fundamental Exam 900

Question

I am getting the following error

We encountered an unexpected error. Please try again later. If this issue continues, please contact site support.

Answer 1

Are you seeing ERROR_VUE_WIDE_BLOCK in the URL when you try and schedule the exam?

ERROR_VUE_WIDE_BLOCK is typically because your account has been blocked by Pearson Vue which normally happens because of multiple failed payments. You need to contact Pearson Vue support using the link on https://aka.ms/CertificationSupport to get the block lifted.

Answer 2

The error message indicates a generic, unexpected error during exam registration. Use the following steps to resolve it:

1. Retry registration following the standard flow
   • Go to the exam’s certification page (AI-900: Microsoft Azure AI Fundamentals) from the certification overview or browse all certifications.
   • On the exam detail page, scroll to “Schedule exam” and select the exam provider (typically “Schedule with Pearson VUE”).
   • Sign in with the Microsoft Learn profile, ensure the legal name is set and matches the ID, then complete the address/phone/email details and click Submit to be redirected to Pearson VUE.
2. Basic troubleshooting for “unexpected error”
   • Close and reopen the browser, then try the registration again.
   • Clear browser cache and cookies before retrying.
   • If using a mobile device, switch to a stable Wi‑Fi connection or try from a desktop browser.
3. If the error persists at the payment/checkout or scheduling step
   • If the error appears on the Pearson VUE side (for example after clicking Submit or during payment), it can be due to an account block such as ERROR_VUE_WIDE_BLOCK, often caused by multiple failed payments. In that case, contact Pearson VUE support using the link provided on the Microsoft Certification Support page so they can check and lift any block.
4. Contact certification support if still blocked
   • If the error continues after the above steps, open a ticket with Microsoft Certification Support so the certification team can investigate the Learn profile and exam registration issue.
