Cannot verify client 3000

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.

Solution 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)

Solution 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.

Solution 3:

This is temporary apple server bug. Try it again OR Retry after some time it will fix the problem. Thanks

Solution 4:

There is no need to reinstall Xcode. Just wait a few minutes and try again and it will work.

Solution 5:

I tried :

• waiting days,
• restarting,
• deleting the developer account in preferences,
• submitting archives from a connected device,
• submitting archives from a iOS generic device.

Nothing worked.

I needed to:

• create an archive (it was from a connected device),
• in the organiser window select the export button (on the right hand side underneath the "Upload to App Store" button.
• Select that the export is for app store distribution.
• Wait.
• Take a note of the location the .ipa file is saved to.
• Go back to Xcode, then select the menu item Xcode > Open Developer Tool > Application Loader.
• Select Deliver Your App, and select choose.
• Navigate to your .ipa file noted above.
• Select next, wait, next, check for any error message, send.

Hope this helps someone.
