Question

Im getting these errors from my app in iOS9. It works great on iOS8. My server is using tls v1.2. So, I dont know where is the problem.

2015-08-04 16:52:24.319 Entumano[676:59469] CFNetwork SSLHandshake failed (-9824)
2015-08-04 16:52:24.324 Entumano[676:59469] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9824)

Answer 1

I got the answer. In all post i read they were talking about tls version. BUT apple it's also validating that your ssl have this ciphers:

TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA 

I manage to workaround setting in plist NSAppTransportSecurity NSExceptionRequiresForwardSecrecy = NO
