If you can traceroute to some unrelated cloudflare dns server like 1.1.1.1, then the problem seems likely to be outside your machine, outside your home network, and then we scrutinize what hop it's failing at to see if we can rule things out further. (I'm making assumptions obviously, this is just how I'd think about it.)
Maybe that's your ISP, or something in a data center with a hostname related to wow itself?
