AdMob IOS Issue getting NSURLSession/NSURLConnection HTTP load failed on AdRequest

I have downloaded the latest Admob SDK from their site and followed the instructions on how to setup and run. On IOS while doing adRequest NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9814) is printed into the Xcode console.
The samething is working fine on android.
Getting the same issue on different devices with different OS version. Tested it on OS 9.3.4 and OS 8.1 same issue.
Have just integrated unity ads into Admob mediation although I have tested others too not working.
Anyone solved this issue or has any lead?

 

allow unsecure http transport in the player settings;
it is NSAllowsArbitraryLoads property of NSAppTransportSecurity key in the property of the XCode project's Info.plist so you can check that too then

 

Has anyone been able to resolve this issue??
I am also facing the same problem, after trying so many things over several weeks still getting the same error.


my .plist contains
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSAllowsArbitraryLoadsForMedia</key>
<true/>
<key>NSAllowsArbitraryLoadsInWebContent</key>
<true/>
