File manager error: 421 Home directory not available - aborting

That was a specific issue with being misdirected in DNS. It’s often a result of an error with an anti-malware firewall or network security filter or whatnot. But that never affects the file manager, let alone the control panel.

This issue is clearly different.

Both are working fine from here. Do you still experience this issue? If so, what do you see?
