• How to Troubleshoot Audio & Video Issues

    If you’re encountering audio or video issues while attempting to watch a course on a browser, this article includes several ways to troubleshoot and resolve these problems. Our Support Team also refers to the troubleshooting steps in this article when responding to inquiries regarding playback issues. 

    Additional resources:

    • Learn more about Udemy’s system requirements. 
      • Please note that a broadband connection with a minimum speed of 5Mbit or 800kbps is required to watch a Udemy course on your device. 
    • Encountering issues while watching courses on or via Udemy’s mobile app? Please review these troubleshooting steps.

    How to check if your playback environment’s causing the issue

    To determine whether your device, settings or internet connection may be causing the problem, please do to the following:

    • Check your network configuration by using our system check and follow any troubleshooting steps that are recommended.
    • Try watching another lecture or course (if you are only enrolled in one course, you can use the course preview feature)

    If you’re able to watch other lectures without any problems, this may indicate there is a technical issue with the original video. Please contact support so our team can investigate further and report the issue.

    If you’re encountering playback issues with other lectures, however, then please try the troubleshooting steps below. 

    How to resolve audio and video issues with your playback environment

    If you’ve determined the problem is due to an issue with your course playing environment, please do the following:

        • If the video plays without issue, try checking your extension, plugin or firewall program on your device to see if it needs to be reconfigured or disabled.  
    • Try a different browser.
        •  If you’re not already using Google Chrome, we recommend using it, as we’ve found it works best to watch Udemy courses. 
    • Update your browser.
        • If you have a lot of browser tabs open, close most of them except the one you’re using to watch the course.
    • Test your internet connection speed.
    • Turn off any hardware acceleration you have installed (in Firefox or on Windows). 
    • Check your audio settings.
      • If you can’t hear any audio, double check to see that the course player volume is turned up and that the video is not muted. Check the sound settings on your device.
    • Restart your computer and network devices (modems/switches/routers).

    Are you encountering a “Problem with your system settings” error notification?

    If you’re encountering an error notification while viewing courses, which states there is a problem with your system settings, please try the troubleshooting steps below.

      1. Update your browser to ensure you’re using the latest version.
      2. If you’re on Google Chrome, Mozilla Firefox, or Microsoft Edge, please verify that you are allowing protected content to play on your device. If any of these settings are disabled, then once enabled, clear your browser’s cache once more prior to checking if video content will now load.
        • Learn how Chrome users can manage protected content. You must allow sites to play protected content. If you are using Google Chrome in a Windows environment, you will also need to allow sites to identify your device.
        • Learn how Firefox users can manage protected content. The Widevine Content Decryption Module provided by Google Inc. must be set to ‘Always activate’.
        • Edge users can navigate to edge://settings/content/protectedContent and ensure that both settings for playing protected content and identifiers for protected content are toggled to the ‘On’ position.
      3. If you’re using Google Chrome 90 or above and the above steps don’t resolve the issue, please enter chrome://components/ into the URL bar at the top of your browser.
      4. Next, navigate to Widevine Content Decryption Module.
      5. Update the Widevine Content Decryption Module so that the version number is 4.10.2198.0 or greater (and, or, the status reads it’s up-to-date).

    Next steps?

    If you’re still encountering issues after following the steps above, please contact our Support Team. In the interim, if the course is available for downloading, try watching it offline or on the mobile app.

  • Troubleshooting Log in Issues

    If you’re having difficulty logging into your Udemy account, this article includes troubleshooting steps you can take to resolve common log in issues and resume your learning experience!

    Log in issues

    Troubleshooting steps for login issues

    I don’t remember my password.

    If you can’t recall the password for your Udemy account, you can initiate a password reset and log into your account.

    I was notified in a Udemy email that I have to reset my password. Why?

    Our system has a range of different security measures in place to protect your account. If, for any reason these are triggered, the system will automatically ask you to reset your password as a form of account security. 

    The email asking you to reset your password will be sent to you via the no-reply@e.udemymail.com address. 

    • If you haven’t logged in for a while and have received one of these emails in your inbox, please follow the instructions in it to access your account. Once logged in, if you see activity in your account that you didn't initiate, please contact Udemy Support.
    • If you have logged into your Udemy account recently and receive one of these emails:
      • Do not clear the cache and cookies on the browser you were using before proceeding with the email’s instructions.
        • There will be specific instructions for resetting your password in the email. Please be sure to follow all of the instructions.
      • If possible, log into Udemy from the same browser tab you used to reset your password.

    Why am I being told my account doesn’t have a “usable password”, after I reset my password?

    This does not mean there’s something wrong with the password you set. As noted above, a range of different security measures are in place to protect your account. If after resetting your password, you see a notification indicating your account does not have a usable password, this could indicate the detection of unusual activity. 

    If you’re encountering a notification stating your account doesn’t have a “usable password”, please do the following:

    1. Check your inbox for an email from our team indicating your account is in safe mode. If there are multiple emails with the same message, please open the most recent one.
    2. Do not clear your browser cache or cookies before proceeding.
    3. Wait 10 minutes and proceed with the instructions outlined in the most recent email from our team. There will be specific instructions for resetting your password in the email. Please be sure to follow all of the instructions.
    4. Then, if possible, log into Udemy from the same browser tab you used to reset your password.

    The Udemy site is reporting I’ve “exceeded the maximum number of requests per hour”, after I tried to log in. What should I do now?

    As a security precaution, if the system detects there have been several, unsuccessful log in attempts, the log in tool will be temporarily disabled. You should be able to log in, however, by initiating a password reset.


    Why am I seeing “There was a problem logging in. Check your email and password or create an account”?

    This error sign indicates our system cannot find an account with login credentials that match the password and email address that have been entered. If you have signed up for Udemy before, and have an active account, please try the following:

    1. Initiate a password reset with the email address you believe is registered for your Udemy account.
    2. If you can’t recall which email address you used to sign up, please try the troubleshooting steps below to determine what email address is registered in your account.

    I don’t recall which email address I used to create my account.

    Learn how you can check which email address is registered to your Udemy account.

    I’m having trouble logging in using the Apple, Google or Facebook options

    In order to log into your Udemy account, you will need to use the same method you used to sign up. Review how to log in with the Apple, Google or Facebook options.
