Probably the most impossible bug of my career was that our static website didn't always load in iOS. I don't mean the page rendered wrong or a script broke. I mean that Safari just said "no, I can't load this page".
It ended up being an issue with the load balancer, that only affected some iPhones.
Eventually I tracked it to the load balancer as hitting hosts directly worked fine. Also, the dev/QA environments worked fine since there was no balancer, For a while devops would argue it was the application team's fault :)
Basically this, except at the time (2017 or so) Google wasn't as helpful:
