I managed to fool them past one thing: The fake error number isn’t visible. Also, they ask for what you were doing when it popped up. I just said I clicked a link and it popped up; he muted for a bit, unmuted, and hung up.

Weird. They may have got suspicious of you. They usually pay someone to put those popups in places, and this popup might have come from typosquatting, ads, etc., and they were told that to eliminate trolls.
