Cannot verify client 3000

Question

I am using xcode 7.1 and trying to upload my app to the app store directly through xcode. While uploading I am getting a weird error:-

cannot verify client 3000

Note:- I recently made changes in the accounts (xcode preference section). Is this related to my error?

I also restart the xcode but issue still there?

I already checked this question on SO, but they say restart your xcode. But this does not solve my problem.

Answer 1

For my case,I got this error after selecting "Generic iOS Device" when archiving, however i plugged in my iPhone and selected it, then archived, I got no errors this time.(I also cleaned both Shift+cmd+k and Shift+alt+cmd+k before archiving)

Answer 2

I encountered the same issue the first time I tried to submit to app store with the target on my device.

What worked for me:
I retried a couple of minutes later without changing a thing and everything went smooth.
