Videos not playing for a user

I have a user experiencing the following error when they play videos (yet no one else is experiencing this). Anyone know what might be going on?

I am no expert but I believe there might be a corryption problem or some feature unsupported by the client’s browser.

It’s definitely on the user’s end as no on else is experiencing this… but not sure what to tell them.

Check the usual :

  • what browser ? version ? up-to-date ?
  • no extension ? ad-block ? darkmode ? etc…
  • try to have him do a screenshot of the console and see if any specific errors
  • maybe
