I have Nokia Lumia 930 with official Windows 8.1 + Lumia Cyan. I am also a member of Preview for Developer and I am currently enrolled. But when I run the "check for updates" it gives me the error. What could have possibly wrong?
According to Windows Phone Community the error means, the server is busy and try again after 10 - 15 minutes. I did try but still got the same. I also restarted my phone by turning it off and on again, is there difference if I restart with (Volume Down) + (Power)?
