Problems with

Lab sign-in failures, lab VMs not loading, or repeated timeouts during Microsoft Applied Skills assessments are handled as technical issues with the assessment lab environment.

Use these steps:

1. Verify local setup
   • Confirm browser meets the Assessment lab technical requirements (supported browser, no aggressive ad/script blocking).
   • If the lab hangs or times out, open a new InPrivate/Incognito window and try launching the lab again.
   • If still failing, clear browser cache/cookies and retry.
2. Check network conditions
   • The screenshot shows relatively low bandwidth; unstable or slow connections can cause lab VMs to time out or fail to load. When possible, use a wired or more stable connection and close other bandwidth-heavy apps while attempting the lab.
3. If the lab session is already locked or expired
   • Wait for the automatic reset window (typically up to 24 hours) to complete before starting a new attempt.
4. Contact official support if problems persist
   • For repeated timeouts, inability to sign in to lab computers, or if the lab never loads even after waiting for reset and trying a clean browser session, use the Credentials Support channel listed under Microsoft Applied Skills Credentials and Assessment Labs to open a support request.
   • For issues specifically with launching the assessment lab or meeting technical requirements, review the Assessment lab technical requirements and related FAQs, then escalate via Credentials Support if the guidance does not resolve the problem.

These channels are the supported way to get individual lab attempts reviewed, extended, or reset beyond the normal 24‑hour cycle.
