We have the same issue all day without resolve. iOS sandbox works fine, macOS sandbox returns this error on authentication attempt.

We experience the same too. Sporadic ETIMEDOUT on verifyReceipt, non-sandbox environment. Our timeout is 120s which we had no problem with ever, but since Jun 14th started getting timeout responses.

Hi, I've had the same issue just now. It seems that something is wrong with provisioning profiles, they got invalidated or something. Anyway, regenerating them helped. If you have 'Automatically manage signing' enabled in your project then you could do the following. Close Xcode rm -rf ~/Library/MobileDevice/Provisioning\ Profiles/ Open Xcode and wait until it updates profiles Try submitting the app again In my case the issue was gone after the profiles were updated.
