Common Video Playback Issues and Solutions

Modern computers simultaneously download, decode and stream media. This process requires capable hardware, updated/compatible software and a strong internet connection.

In this post, we’ll review some common video playback issues experienced by HuskyCT users and how to resolve them.  The most likely culprits are often your browser/device settings or network connection.

Before we dive into specific issues and resolutions, let’s take a look at a few quick-fix solutions when time is of the essence (when is not, right?)

Try these quick fix solutions!

  1. Try a different browser.  Many times the culprit is a setting or cache issue in your preferred web browser.  While this fix doesn’t resolve the issue in your primary browser, it might solve the more immediate issue – finishing your assignment!
  2. Clear your browser cache, close and restart the browser.  Most video playback issues are resolved by refreshing your browser cache.  Step by step instructions for clearing your browser cache can be found at
  3. Restart your computer.  This is the “Hail Mary” of solutions!  If the underlying issue is caused by a runaway or malfunctioning system process, memory or other system issue, a restart can be surprisingly effective.
  4. Verify your browser security hasn’t blocked the video due to “mixed content” (does not apply to Safari).  This blog post has hints and solutions for identifying and resolving “mixed content” blocking!

If none of the above solutions work, check with classmates to see if they experiencing similar playback issues.  If they are, notify your instructor and provide detailed feedback.  Alternatively, you can seek assistance from the UITS Help Center.
