It catches tech literate people's bugs so often too. I maintain my teams VPN, and I have a script that I ask people to run to generate logs when there's an issue. It checks connectivity, flushes DNS, restarts the VPN and toggles the network device off and on again, then checks connectivity again. The only person so far who this didn't fix the issue for (on an engineering team) was someone who had another VPN client installed and running, despite their insistence that they had followed the setup instructions clearly. That person was an engineer working on infrastructure and online services.
