Overview of troubleshooting tools to solve technical issues for the teacher

Remember that LearnCube works by allowing you and your students to stream video/audio through your web browser.

What you need to teach using LearnCube:

  1. A relatively modern computer (we support PCs less than three years old)

  2. A modern web browser (e.g. Chrome or Firefox)

  3. A reliable internet connection

So if you're experiencing an issue, it's likely linked to one of these areas. Click the links to go to the solution.

The most common issues and causes are:

  1. Can't enter the class? Have you clicked Enter Class, or could there be a firewall preventing you? 

  2. Can't see your students? Have they allowed their video? Use our in-class diagnostics tool to solve. You may want to ask students to redo their equipment tests from settings.

  3. Can't hear your students? Have they allowed their microphone? Do they need to change to the mic on their headphones?

  4. Your students can't see or hear you? Have you allowed your webcam and microphone? If some, but not others, can hear you - perhaps try reconnecting the video/audio here

  5. Are you noticing an echo? If you're teaching a group class, does everyone have headphones

  6. One student's connection is fragile and distracting others? You might need to control the student's mic/webcam or remove the student.


We have developed a set of useful tools that can aid you in preventing, diagnosing, checking, and investigating any problems.

  1. Troubleshooter (to prevent)

  2. Speed test (to check)

  3. Post-class review  (to investigate)

If you have tried all of these tools and resources and still encounter issues, kindly take a screenshot of the error and provide a brief description of the expected outcome versus what actually happened. You may then send it to us at Be sure to capture the entire screen, including the URL. If the issue occurred during a class, please also include the class review link.
