I'm developing an app using cordova (5.2.0).
On mac I'm using Xcode 6.4 to generate the .ipa
At some point I initialize a secure websocket connexion (certificates are not self signed, length is 2048) like this in js:
socket_ip = new WebSocket(wss://perform.domain.com:8080, "image-processing-protocol");
The connexion is working on Android and also from desktop browser (safari too).
However, from my Iphone(8.4) I got a :
CFNetwork SSLHandshake failed (-9807) which means "Invalid certificate chain"
On server side the message I got is:
error:00000005:lib(0):func(0):DH
My sever configuration is:
info.ssl_cert_filepath =
"sslCertificates/myCert.cer";
info.ssl_private_key_filepath ="sslCertificates/myCert";
info.ssl_ca_filepath ="sslCertificates/GlobalSignRootCA.cer"
info.ssl_cipher_list ="RC4-SHA:AES128-SHA:HIGH:!aNULL:!MD5"
Looks like my issue is similat to openssl-ssl-accept-error-5 . I then tried to set up a cipher list without DH but I still got the error.
I am probably missing something to configure on my libsocket server.
As long as I'm using a commercial certificate and it's working with other devices I don't understand with the connexion with IOS failed.
Any Help would be much appreciated, Thanks!
Is there an intermediate certificate from GlobalSignRootCA that you also have to add?
I did the checks as Steffen suggested.
Solution was to set elliptic curve Diffie Hellman protocol up within libwebsocket.
Thanks for your help.

I have a problem with SSL Pinning on iOS. I was using the following plugin:
https://github.com/silkimen/cordova-plugin-advanced-http
and
https://ionicframework.com/docs/native/http
This method is working fine for Android. However, with iOS, I am receiving the following error on Xcode:
Connection 1: default TLS Trust evaluation failed(-9813)
Connection 1: TLS Trust encountered error 3:-9813
Connection 1: encountered error(3:-9813)
I am not sure how to fix this problem. I've googled everywhere, and most of the solution is for Android, and not iOS specifically.
Any help is very much appreciated. Thank you.
I am trying to send push notifications, to iOS Devices which was working pretty well, but suddenly it started throwing the following error:
stream_socket_client(): SSL operation failed with code 1. OpenSSL
Error messages: error:14094438:SSL routines:ssl3_read_bytes:tlsv1
alert internal error
I checked with server port 2195 and 2916 both are enabled and double checked the .pem file which seems correct too.
I would appreciate if I can get help on the above error.
Thanks
Hi you should export Apple push service certificate screen shot given below and export it, Iam also got same error now fixed by export this certificate.
Let me know if you have any clarifications.
This issue happens only in iOS 11 But works fine in other versions
So this question is not a duplicate and need to know what could be the cause
Issues details:
I am using a 3rd party library(private) & the issue happens in it.
When we debug the results from the library call we found the following issue log,
The certificate for this server is invalid. You might be connecting to
a server that is pretending to be
“DOMAIN.com” which
could put your confidential information at risk
But if the issue occurs in iOS 10 and below it would be fine and would have decided its common issue. But since it occurs only in iOS 11 I wonder why, Any suggestions or solutions please ?
My code for ssl handshake fails since I updated xcode to 6.4 (and simulator to ios 8.4). The error is: CFNetwork SSLHandshake failed (-9850)
The same code is performing ssl handshake successfully on ios 8.3 simulator (i've also tried ios 8.3 simulator from xcode 6.4 and it handshakes well).
Here's the piece of code that cofigures and starts handshake. I'm using swift.
self.socket.startTLS([kCFStreamSSLLevel:kCFStreamSocketSecurityLevelTLSv1,
kCFStreamSSLValidatesCertificateChain:kCFBooleanFalse])
I was trying to figure this out whole day and I couldn't even find out what the error code -9850 means. It isn't listed with all the other codes in SecureTransport.h file.
Update1:
I found out that apple introduced app transport security which means that you can declare domains you want to establish secure connection to. Anyway I tried with ATS but without any success. -9850 error is still making problems.
Update 2 - Solution
As Michal and Steven suggested in their answers I started to suspect that the main issue is on the server side which ended up to be true.
I talked with guy who implemented the server and all problems were gone after he generated new ssl certificates of length 2048. Before that they were 512. With new certificates, code on my side works perfectly fine.
-9850 appears in the SecureTransport.h header buried inside the iOS 9 SDK:
errSSLWeakPeerEphemeralDHKey = -9850, /* weak ephemeral dh key */
It sounds like Michal is on the right track. A more general search for this problem led me to http://www.chromium.org/administrators/err_ssl_weak_server_ephemeral_dh_key:
As of Chrome 45, this error message is triggered if the SSL/TLS handshake attempts to use a public key, smaller than 1024 bits, for ephemeral Diffie-Hellman key agreement.
I'm not saying that iOS 9 imposes exactly the same requirements as Chrome, but I'd start looking at the server configuration and if you can increase the key size it uses for the SSL handshake.
I believe it has something to do with coreTLS:
Description: coreTLS accepted short ephemeral Diffie-Hellman (DH) keys, as used in export-strength ephemeral DH cipher suites. This issue, also known as Logjam, allowed an attacker with a privileged network position to downgrade security to 512-bit DH if the server supported an export-strength ephemeral DH cipher suite. The issue was addressed by increasing the default minimum size allowed for DH ephemeral keys to 768 bits.
From what I can tell from your code, I guess you're using GCDAsyncSocket. It has been updated 10 months ago, so it definitely does not reflect this issue.
When I get CFNetwork SSLHandshake failed -(*) its because my device is connected to the network but not the internet.
Some times i'm getting CFNetwork SSLHandshake failed -(9806) in my code,but i'm not sure why this is happening as my code runs smoothly,except when i run it in iOS 6 and then on iOS 7 64-bit i get this warning.
Can anybody suggest me, how to handle this issue ?
Normally when I get CFNetwork SSLHandshake failed -(*) Its because of my local wifi network (device is connected to network but not the internet)
Try it again on another network (3G is the quickest solution for me)
This could also happen because of iOS 9. iOS 9 and OSX 10.11 require TLSv1.2 SSL for all hosts you plan to request data from unless you specify exception domains in your app's Info.plist file.
You can find more info here:

Or Steven Peterson's answer here, which is quite clear:
https://stackoverflow.com/a/30720929/1485701
Had the same issue and after I have confirmed that the server is getting the POST the solution was this:
Clean the project: Product -> Clean
Delete your app from the iOS device/iOS Simulator and quit the Simulator
Compile your app and run it
In my case, simple as that.
I had the same problem, and in my case the solution was that in my code I wrote
initWithScheme:#"https"
instead of
initWithScheme:#"http"
So make sure you use the correct protocol
Another solution: check if date/time is set correctly in your phone. SSL certificates are valid UNTIL certain date.
