Do you have any browser plugins that may be blocking the page from loading?
VPN
Do you currently have a VPN running in the background? Does turning off the VPN successfully log you in? Not sure if a VPN would block access, sometimes VPN sevices have their own firewall rules that interfere so it's a good one to rule out.
Trying to rule out anything due to being on the home network.
