server down for maintenance. come back tomorrow.

but i had the problem since yesterday's noon

until 3am la.. after 3 try.

Server maintenance now. u better try it tomorrow morning.

if it still fail,
Try deleting the file from
C:\Program Files (x86)\Diablo III\Updates

and re-open D3

I don't think is maintenance problem. I had the problem as well. I'm using a mac and i uncheck auto proxy discovery and problem solve.

Try unchecking that if windows have it.

i'm using mac.. My 5cent advise just wait until the maintenance finish..

i agree

try delete blizzard n battlenet folder in C:/programdata . but do it tomorrow
