This article is for faculty, students and staff who are experiencing issues with video playback in HuskyCT. The most common causes for issues with video playback are often your browser/device settings or network connection.

Getting Started

Below are some quick-fix solutions. You are encouraged to try each of these solutions first. 

  • Try a different browser.  Many times, the cause of the problem is a setting or cache issue in your preferred web browser. 
  • Clear your browser cache,  and close and restart the browser.  Most video playback issues are resolved by refreshing the browser cache.
  • Restart your computer. If the underlying issue is caused by a runaway or malfunctioning system process, memory or other system issue, a restart can be surprisingly effective.
  • Verify your browser security hasn’t blocked the video due to “mixed content” (does not apply to Safari).

If the issue you are experiencing with video playback persists, check with others to see if they are experiencing similar playback issues. If they are experiencing similar issues, notify your instructor and provide detailed feedback. If others are not experiencing similar issues, proceed to the other troubleshooting sections below.
