how to fix unexpected-error?s=ERROR_VUE_WIDE_BLOCK

ERROR_VUE_WIDE_BLOCK indicates that the Pearson VUE system has blocked the account, typically due to multiple failed payment attempts. This block prevents scheduling exams such as AZ-900 and causes the “unexpected error” message during registration.

To fix it:

1. Check whether ERROR_VUE_WIDE_BLOCK appears in the browser address bar/URL when the unexpected error occurs.
2. If it does, the block must be removed by Pearson VUE support; it cannot be cleared through the Microsoft Learn or Pearson VUE self-service pages.
3. Contact certification support using the support entry point at:
   • https://aka.ms/CertificationSupport
4. Explain that ERROR_VUE_WIDE_BLOCK appears when trying to schedule AZ-900 and that you need the Pearson VUE block on the account reviewed and lifted.
5. After Pearson VUE confirms the block is removed, return to the exam registration flow and try scheduling the AZ-900 exam again.

If the error persists and ERROR_VUE_WIDE_BLOCK is not present in the URL, open a case with Credentials support for further investigation:
