I am also having difficulty signing in to cpanel / direct ... Tried yesterday and today, still the same message:
Please standby while transfer you to your web hosting account.
An error has occurred forwarding your sign in. Retry
I did the Win10 upgrade and almost immediately found an issue with the graphics despite my computer being "suitable for Windows 10".
Battled on for a few weeks then I think I encountered some other problem which appeared to be a very common glitch so gave up and went back to Win7Pro.
Yeah, my websites are all down as well. When I log in it normally says "Access C Panel" but all I get now is "Standby".
