Could you please try connecting to the control panel over a VPN?
After the DDoS attack on the control panel last week, we moved traffic to a different network that allows us to have better DDoS protection. It’s possible that either our DDoS protection is blocking access to you, or something on your network is blocking access to our new network provider for the control panel.
Could you please also try making a traceroute from your own computer to cpanel.epizy.com (without a VPN) and share the results here? That may give us a better idea about where this block could be.
