The line comes from an older Poupou video that has since been deleted, where the phrase became a running joke among viewers who recognised it as the default answer to almost any connection problem. Even after the original video disappeared, the short audio kept circulating on soundboards, where French-speaking creators reuse it as shorthand for unhelpful troubleshooting. Its staying power comes from that shared experience: almost everyone has been told to restart their box, regardless of the actual fault, so the clip still works without any extra context.
