I have created a REST API with node.js and express. I am now trying to connect to the backend with a secure connection using Alamofire 3/https/SSL/TLS. I have a CA signed certificate, with a 2048 bit key installed on the server with the 'https' npm module. The error the server returns in xcode is below: 1
When I evaluate my SSLLabs it says certificate signed and TLS 1.2 / 1.1 all available etc as seen below. However interestingly under where it simulates requests the request record for iOS 9 (ATS) - Fails with 'Sever closed connection' as seen in the image below.
TLS connection completed successfully2
iOS 9 simulated request fails [3]
When I use the command:
nscurl --ats-diagnostics --verbose
Everything passes except the Default ATS Secure Connection and all three TLS exceptions as seen below:
ATS Default Secure Connection Failing[4]
3 TLS exceptions failing[5]
I am not sure what else to try as far as I understand I meet the requirements for ATS :
- TLS v1.2
- Forward Secrey (I am not sure how to test this)
- At least a 2048 bit key -
When I turn on CFNetworking logging in the logfile it points to Error code -1200 in CFNetwork/CFNetworkErrors.h which has the error reason 'The secure connection failed for an unknown reason.'
I am at a lost as to what to try next, thanks. Sorry it will only let me post 2 links so I had to remove some images.
