Admob ios 11 handshake issue

I am trying to use Admob plugin but i’ve got an following errors:

2017-12-31 14:50:05.026589+0500 cyber-vortex-mobile[4091:1582149] [BoringSSL] Function nw_protocol_boringssl_handshake_negotiate_proceed: line 387 Handshake failed. Disconnecting the session

2017-12-31 14:50:06.178220+0500 cyber-vortex-mobile[4091:1582112] NSURLConnection finished with error - code -1200

My applicationDidFinishLaunching code:

...
#if CC_PLATFORM_IOS
    sdkbox::PluginAdMob::init();
    sdkbox::PluginAdMob::cache("gameover");
#endif

return true;

In my sdkbox_config.json i have the

"ios": {
    "AdMob": {
      "test": true,
      "ads": {
        "gameover": {
          "type": "banner",
          "id": "--MY-ID--",
          "alignment": "center"
        }
      }
    }
  }

maybe http://docs.sdkbox.com/en/plugins/admob/v3-cpp/#disable-app-transport-security

Seeing the similar problem. Ads were working before but recently stopped working.

I have NSAppTransportSecurity set in a .plist file

Here is some logs:

which plugin version u use?

Apparently, admob fails to load only when the internet connection is slow.

cocos2d-x 3.13.1

SDKBOX Inc. v1.0.1.30
installed packages:
v2.3.17.3 sdkboxads
v2.3.17.3 chartboost
v2.3.17.3 admob
v2.3.17.3 googleplayservices

So, this issue is network related. Or It’s not a issue.

Should be network related.
