Kaltura - Known Issue - Privacy and ad-blocking software can cause issues with Kaltura MediaSpace

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.
  • 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.

Status

Issues with these privacy or ad-blocking software and hosts lists still exist as of 5/20/20.

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 issues the user should remove Kaltura related sites from their hosts file. For example kaltura sites should not be redirected to 0.0.0.0. These are some example domains which should not be redirected to 0.0.0.0:
  • stats.kaltura.com
  • analytics.kaltura.com
  • cfvod.kaltura.com
  • cdnapi.kaltura.com
