Kaltura - Known Issue - Privacy and Ad-blocking Software Can Cause Issues with Kaltura MediaSpace [UW-Madison]

This document describes potential issues privacy or ad-blocking software may cause users when trying to view Kaltura MediaSpace content.

Affects

This affects users who are running privacy or ad-blocking software. Examples of software and host lists that we've received reports on that can cause issues with Kaltura MediaSpace videos include:
  • AdBlock Plus - AdBlock Plus may stop playback of some Kaltura media and stop collection of Kaltura analytics.
  • uBlock Origin - uBlock Origin may stop collection of Kaltura analytics.
  • Ghostery - Depending on your privacy settings, Ghostery can cause the Kaltura MediaSpace player to display Unknown uiConf[0] error or Ghostery blocked Kaltura video player error.
  • Privacy Badger - will cause uploads to timeout.
  • Curated host lists - for example the StevenBlack/hosts list - will cause the Kaltura MediaSpace player to display {"Error ["type":"networkError","details":"levelLoadError","fatal":true,"networkDetails":{} error.
  • Firewall filters - Some users may setup filters to block Kaltura domains in an effort to block ads. Unfortunately this also impact Kaltura's ability to serve videos to users and may result in a blank screen or a video not loading.

Workaround

Workarounds will vary based on the privacy or ad-blocking software the end-user is using. If it is possible to allow Kaltura domains or disable the software for UW-Madison Kaltura (mediaspace.wisc.edu) and Canvas (canvas.wisc.edu) please try that.
To resolve hosts file or firewall issues the user should remove Kaltura related sites from their hosts file or firewall settings. For example kaltura sites should not be redirected to 0.0.0.0 or blocked by a firewall. These are some example domains which should not be redirected to 0.0.0.0 or blocked by a firewall rule or filter:
  • stats.kaltura.com
  • analytics.kaltura.com
  • cfvod.kaltura.com
  • cdnapi.kaltura.com
