I've been having issues for almost two months now, I noticed it's only whn i'm using a residential Ip address. As soon as I switch to VPN it works normally, it also works on mobile connections. i tested WIFI only on my phone with my home ip and the site failed to load. the annoying thing about it is it's intermittent when it works or doesn't work from a residential IP. So use a VPN or use a web browser with a free vpn like Opera
