For a Microsoft Applied Skills assessment lab that does not open, use these supported steps first:
- Check connectivity readiness by launching the Lab Orientation & Connectivity Check.
- If the affected users are on work-issued devices, try a personal device instead. Work-managed device policies can block remote lab sessions.
- If the lab is being accessed from a managed work or school network, have IT review the published Connectivity Requirements.
- If the lab shows a blank or black screen, or input is delayed, treat it as a possible connectivity issue even if the in-lab latency indicator looks good.
- Try signing out of active browser sessions, clearing browser cache, then retrying.
- Retry in an InPrivate/incognito window or a different browser.
If the issue continues, open a Credentials Support case:
- Go to online support request.
- For Product family, select Learning.
- For Product or Service, select Microsoft Credentials.
- Choose the category that best matches the issue.
- For Types of Support, select Professional No Charge.
- Enter location and time zone.
- Select Email as the preferred contact method. Credentials support is provided by email, not phone.
- In the case details, include:
- the Applied Skills assessment name
- a clear summary of the VM launch failure
- reproduction steps
- screenshots of the error
- the user’s Learn Username from Learn Settings
After submission, a case number is shown and also confirmed by email. Case status can be checked from the Manage tab of the online support request site.
