I've been having issues getting league of legends to start when I'm on my Virgin Media connection. I can get things up and running fine when I'm hotspotting onto the phone, but can't get past the update server check when I'm on wifi.
It looks like there is partly an issue with Cloudflare that is blocking access to sites under it's protection with a security check. And because the updater just sends a request without caring about a response page, it falls over and dies.
Anyone happen to know the URL/domain for the riot games updater?
