I want to find out a way to locate the exact failed request.(CFNetwork SSLHandshake failed (-9806))

Question

I got an error log in my console CFNetwork SSLHandshake failed (-9806) by xCode.

How can I figure out which request is responsible for the failed log.

There are many requests both third party and my own server request when my app launched. I can not figure out which one having error.

Log console only gives me CFNetwork SSLHandshake failed (-9806)

ps: I'm using swift 3.0, Xcode 8. AFNetworking 3.0(seems request by AFNetworking don't have error, cause I use AFNetworking logger to log all request by AFNetworking )

when testing, iOS 8 and iOS 9 seems like make more failed logs than iOS 10.

ps: I have add NSAllowsArbitraryLoads to my plist file, And many of my https and http requests have load successfully.

I think you have not added following in info.plist

<key>NSAppTransportSecurity</key>
   <dict>
       <!--Connect to anything (this is probably BAD)-->
       <key>NSAllowsArbitraryLoads</key>
       <true/>
   </dict>

If not added, then please add this, so that you will not get this error.
