It's hard to say without knowing which was the last version of MonoTouch was used to build your application. However all major changes are documented in the release notes [1]. My guess would be the fix for bug #5546 [2]. [1] http://docs.xamarin.com/ios/releases/MonoTouch_5 [2] https://bugzilla.xamarin.com/show_bug.cgi?id=5546 > System.Net.WebException: Error getting response stream (Write: The > authentication or decryption has failed.): SendFailure > ---> System.IO.IOException: The authentication or decryption has failed. > ---> Mono.Security.Protocol.Tls.TlsException: Invalid certificate received > from server. Error code: 0x5 The 0x5 is one of the error code [3] that iOS returns when it dislike the X.509 certificate that it received from a server [4]. Now the value 0x5 (kSecTrustResultRecoverableTrustFailure) is not a fatal error but a warning that things are not totally correct (see some possible conditions documented in [3]). In such case you should check the certificate yourself and/or ask the user for confirmation (there are callbacks for this [5], and you can cache this answer to avoid asking over-and-over again).
