I have Xcode 5, I have tried to validate my app but these communication errors were found:
Communication error. Please use diagnostic mode to check connectivity. You need to have outbound access to TCP port 443.
An exception has occurred:Remote host closed connection during handshake
An error occurred while invoking service method:authicateForTransportDiscovery
An exception has occurred:null
Could not connect to Apple's web service
An error has occurred while invoking service method: validateMetadata
Unable to authenticate the package: 96850972.itmsp
Any ideas?
