August 7, 2026: Identified | VMs – Black Error Screen
We have received multiple reports of an unexpected black screen occurring during the startup and operation of virtual machines on ACI Skill Labs. Our team has identified the cause and is working with a third-party vendor to resolve the issue. We will provide an ETA as soon as one is available.
We will update this page as soon as we have more information. Thank you for your patience while we work through this

Next Steps
Students who encountered this issue:
- Log out and log back in, then relaunch the lab
- If the black screen appears again, close the lab session and try launching it again rather than repeating multiple attempts in a row
- If the issue continues after a second attempt, contact ACI Learning Support at skilllabs.support@acilearning.com with the lab name and approximate time it occurred so our team can investigate
Students with persistent labs:
- Your lab data and progress are not expected to be affected by this issue
- Avoid repeatedly restarting or resetting your persistent lab while we investigate, as this is unrelated to the fix and won't resolve the black screen
- Please stay tuned to this page for updates, and reach out to Support if you need to access a specific lab urgently
