What if a course video or material isn’t working?
Updated at Feb 6, 2026, Viewed 0 times
If you encounter issues accessing or playing your course videos or materials on the ACLAS platform, don’t worry, as most problems can be resolved quickly by following these steps.

Step 1: Check Your Internet Connection



Ensure you have a stable and high-speed internet connection.

Try refreshing the page or reconnecting to your Wi-Fi or mobile data network.

Slow or unstable internet is one of the most common causes of playback issues.

Step 2: Try a Different Browser



For the best experience, we recommend using Google Chrome, Microsoft Edge, or Firefox.

If you’re already using one of these browsers, try:

  • Clearing your browser cache and cookies.


    • Restarting the browser.

    • Opening the course in incognito or private mode.

    Step 3: Disable VPN or Browser Extensions



    Some VPNs or browser extensions (especially ad blockers or privacy add-ons) may interfere with loading course materials.

    Please turn off your VPN or disable browser extensions temporarily and reload the page to check if the content works properly.

    Step 4: Try a Different Device



    If the problem persists, try accessing the course from a different device (e.g., from your phone, tablet, or another computer) to check whether it’s a device-specific issue.
