We completely understand how important it is to have smooth and reliable access, and we’re here to help you navigate this issue with clear steps and support.

This error typically means that your current login credentials or access permissions aren’t allowing you to view the content. This can happen for various reasons, including account status, IP restrictions, or authentication problems. Please see the walkthrough and some simple troubleshooting steps you can try on your end.

Basic Troubleshooting Steps for 401 Unauthorized Error

  1. Double-Check Your Login Details
    Please ensure you are entering the correct username and password. Sometimes a small typo can cause access issues.

  2. Verify Your Access Permissions
    Kindly confirm with your institution that your account is active and has the proper permissions to view the content.

  3. Check IP Address or Domain Restrictions
    Many institutions restrict access based on IP addresses or domains. Please ensure that your current network’s IP address is included on the approved list. If you are a student, kindly reach out to your professor or IT administrator to verify your IP access.

  4. Try Accessing JoVE from a Different Network
    If possible, please switch to another internet connection, like home Wi-Fi or mobile data, to rule out network restrictions.

LMS (Canvas/Moodle/etc.) Authentication Mismatch

Why This Happens

A 401 error inside the LMS can occur if:

  • The LMS sends an invalid or expired LTI launch token

  • The user switches browsers or devices mid-session
