Than it could be problem with your service provider maybe connection is not accepting access request from server. You should have to reboot your modem and clear browsing history and cache I hope you will get access to this website or you can use some alternative ways like VPN to get access to your account.
I tried on several different places/PCs, with different browsers and providers, also mobile devices and 4G. Same problem.
Yes VPN or something I could try, but then again, is it worth it, I mean it's not on me to go through all these steps, they should fix this long standing problem, not me...
