Getting “Cannot verify client. (3000)” when trying to upload archive from Xcode to itunesConnect

Question

Just updated to Xcode 7.1 and getting this error. Was able to upload fine using 7.0.1

Answer 1

Exporting the app as an .ipa and uploading via Application Loader 3.0 worked for me. (Restarting xcode, cleaning, and re-archiving did not.)

Answer 2

I've been having this problem since Xcode 7.1 (for more than a month). I did everything I could trying to solve this: restart Xcode, clean project, clean build folder, build with a device connected, reinstall Xcode multiple times, even formatting the whole disk and starting from scratch. None of this worked.

During this time my colleague was always able to upload the very same builds to App Store without any problem.

Curiously, what solved this problem for me was disconnecting my non-Apple wireless mouse.

I found this out when I tried to submit an app from my home computer and got the same error. I disconnected the mouse dongle, tried again and it went through.

I've verified this three times both on my home (MacBook Pro 2013) and work computer (Mac Mini 2014).

This leads me to believe that during the app submission process Apple may check if your environment is purely made by Apple or not, and may block your submission based on that. This would explain the "Cannot verify client" message.

Answer 3

If you encounter this error, you have two options:

Option A - Engage in an activity that takes a minute or two. Could be any of the activities described in the other answers, like re-install XCode, renew certificates, do a new build from scratch after clearing caches. Or simply go get a coffee.

or

Option B - Do nothing at all for a little while.

Then, try again. If it doesn't work, repeat.

Answer 4

Same problem here. Clean build and deleting project caches worked.

Answer 5

Hmmm, well a restart of Xcode, a fresh clean, build and archive seems to have fixed it.

Answer 6

Just updated to Xcode 7.1 and getting this error. Was able to upload fine using 7.0.1

same here - restart, clean build, archive and upload was successful.
