iOS 9 https calls


I am struggling with a network related issue.
For information I have full access to my server, certificates, API. Everything is hosted by our server using IIS 8

I am aware of the https TLS1.2 limitation from apple on iOS 9 and tried to get it working on my device.

I have got 2 different types of calls : JSONP to get a .txt file, or GET, from my

Both are working fine on “ionic serve -ios” but I have the following result on Xcode : NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9843)

I have check, my ssl certificate and I can see TLS 1.2.

Can someone give me roads to follow to get that working ? Adding my server as an exception didn’t work, allowing everything (in info.plist) didn’t work.

Thanks for any help.
