Undocumented NSURLErrorDomain error codes (-1001, -1003 and -1004) using StoreKit

All error codes are on "CFNetwork Errors Codes References" on the documentation (link)

A small extraction for CFURL and CFURLConnection Errors:

  kCFURLErrorUnknown   = -998,  kCFURLErrorCancelled = -999,  kCFURLErrorBadURL    = -1000,  kCFURLErrorTimedOut  = -1001,  kCFURLErrorUnsupportedURL = -1002,  kCFURLErrorCannotFindHost = -1003,  kCFURLErrorCannotConnectToHost    = -1004,  kCFURLErrorNetworkConnectionLost  = -1005,  kCFURLErrorDNSLookupFailed        = -1006,  kCFURLErrorHTTPTooManyRedirects   = -1007,  kCFURLErrorResourceUnavailable    = -1008,  kCFURLErrorNotConnectedToInternet = -1009,  kCFURLErrorRedirectToNonExistentLocation = -1010,  kCFURLErrorBadServerResponse             = -1011,  kCFURLErrorUserCancelledAuthentication   = -1012,  kCFURLErrorUserAuthenticationRequired    = -1013,  kCFURLErrorZeroByteResource        = -1014,  kCFURLErrorCannotDecodeRawData     = -1015,  kCFURLErrorCannotDecodeContentData = -1016,  kCFURLErrorCannotParseResponse     = -1017,  kCFURLErrorInternationalRoamingOff = -1018,  kCFURLErrorCallIsActive               = -1019,  kCFURLErrorDataNotAllowed             = -1020,  kCFURLErrorRequestBodyStreamExhausted = -1021,  kCFURLErrorFileDoesNotExist           = -1100,  kCFURLErrorFileIsDirectory            = -1101,  kCFURLErrorNoPermissionsToReadFile    = -1102,  kCFURLErrorDataLengthExceedsMaximum   = -1103,

I have similar problems, in my case seem to be related to network connectivity:

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

Things to check:

• Is there any chance that your server is not able to respond within some time limit? Like 60 seconds or 4 minutes?
• Is there a possibility that your device is switching networks (WiFi, 3G, VPN)?
• Could someone (client vs. server) be waiting for authentication?

Sorry, no ideas how to fix. Just debugging this, trying to find out what the problem is (-1021, -1001, -1009)

Update: Google search was very kind to find this:

• -1001 TimedOut - it took longer than the timeout which was alotted.
• -1003 CannotFindHost - the host could not be found.
• -1004 CannotConnectToHost - the host would not let us establish a connection.
