Troubleshooting

How to fix TestOut not working

TestOut is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:

Your browser tries to reach w3.testout.com over your own connection, right now. Nothing is sent to us or stored.

Reload the TestOut lab or exam
Press Ctrl+R, or Cmd+R on a Mac, on the page that failed; if a lab or exam still hangs, close the extra TestOut tabs and open the course again from the dashboard. A single stuck tab often clears after a full reload.
Open the course item in a private window
Open a private window with Ctrl+Shift+N in Chrome or Ctrl+Shift+P in Firefox, then sign in and load the same course item. If it works there, an extension is interfering; turn off extensions one at a time from the browser's Extensions page.
Clear site cookies and cache
In Chrome, open Settings, then Privacy and security, then Delete browsing data; pick Cookies and other site data and Cached images and files, set the time range to All time, then reload the course. Sign out and back in only if the page still fails.
Try another network for lab playback
If labs or exams stall on a school network, switch to a home connection or turn off the VPN, then open the site in a current version of Chrome or Edge. Use one browser tab for the course and check that the browser allows cookies and JavaScript for the site.

While it is down

While TestOut is down: what to use instead

CompTIA CertMaster Learn Use it for CompTIA lessons and practice questions when your course is built around those exams and the lab simulations are unreachable.
Microsoft Learn This covers Microsoft certification topics with reading and exercises if your assigned work is on Windows or Microsoft cloud material and can wait for the lab platform.
Cisco Networking Academy For networking classes that use Cisco material, it offers course content and Packet Tracer labs you can run while the training site is unavailable.
Professor Messer video courses Review CompTIA exam objectives with the videos when you need explanations and cannot open the lab platform.

Same time

Problems at the same time as TestOut

Since 8 November, all 2 of TestOut's spikes in problem reports overlapped a spike at another service.

When several services get problem reports at once, something they share, such as a cloud host or a network, can be the real cause. Matching times alone do not prove it.

About

What happens when TestOut goes down

TestOut is an online learning service for IT training and certification prep, used by US students and instructors in school and workplace programs. An outage cuts off course lessons and hands-on labs that people need for class or exam prep.

You may hit a login loop or a blank course dashboard first; lessons and labs can then fail to launch while practice exams and progress tracking stall. A single course can open while a lab stays stuck on loading. That partial failure looks mild until classwork depends on the lab, and the same fault can hit one campus network or sign-in path while other parts of the site load.

Questions

TestOut FAQ

Is TestOut down right now?

The status at the top of this page shows whether user problem reports for TestOut are above their usual level, counted in 15-minute windows over the last 24 hours; those reports go to a public outage-reporting service, and the status comes only from them. This site does not monitor the service or collect reports itself. To rule out your side, open the same course or lab from another network and device; if only one setup fails while other sites load, the problem is local.

Why does a TestOut lab open to a blank screen or keep loading?

Labs are the interactive part of a course, and they need a desktop browser with pop-ups and third-party cookies allowed. Clear the browser cache and reload the lab from the course list. If it still fails, turn off strict tracking protection for the site and try another browser.

Why am I getting 'invalid username or password' when I log in with a school account?

School or organization logins often use a separate sign-in page or single sign-on, so the password you use for email may not work on the TestOut login form. Try the sign-in link your instructor gave you, and check that caps lock is off before retrying. If other students in the same class can log in, ask your instructor to confirm your course access.

Can I reset a lab or exam attempt after my connection drops?

A dropped connection can leave a lab or exam attempt marked as in progress, and you usually cannot clear that yourself from the student view. Contact your instructor or program administrator with the course name and the time the session failed; they can reset the attempt or tell you whether it will reopen. Do not start a new attempt until you hear back, because duplicate attempts can complicate the review.

Why does my TestOut access code not show the course I bought?

Access codes bind to the account you enter them on, and a code for one course will not open a different course in your dashboard. Sign out and back in, then check the course list from the account that redeemed the code; if the course still does not appear, send the code receipt and your username to the school or store that sold it. Do not create a second account to test the code, because that can make the license harder to trace.

How we track TestOut

The status on this page comes from user-submitted problem reports for TestOut, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for TestOut, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.

When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. TestOut doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
