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

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.

Solution 
  • setenv("CFNETWORK_DIAGNOSTICS", "3", 0)
