Error using afnetworking request

One, request timeout

connection error returned by error:error domain=nsurlerrordomain code=-1001 " The request timed out. "userinfo={nsunderlyingerror=0x1408a8eb0 {Error domain=kcferrordomaincfnetwork code=-1001" (null) userinfo={_kcfstreamerrorcodekey=-2102, _kcfstreamerrordomainkey=4}}, nserrorfailingurlstringkey=http:// 192.168.80.80:8081/router, Nserrorfailingurlkey=http://192.168.80.80:8081/router, _kCFStreamErrorDomainKey=4, _ kcfstreamerrorcodekey=-2102, nslocalizeddescription= request timed out. }

It was always possible to request on the emulator, but when it came to the real machine test, it always gave me an error: The request timed out and no requests were sent out. I and backstage personnel to debug stand-alone, is also useless, the backstage staff told me that the request did not jump into his breakpoint.

The final troubleshooting reasons are: My simulator and computer are connected to the company's internal wireless network, while the mobile phone is connected to the guests of the wireless network, two wireless network is not the same segment (Network segment (network segment) generally refers to a computer network using the same physical layer equipment (transmission media, Repeater, hubs, etc.), which is able to communicate directly to the part of the end, I sought to get the tube and the simulator on the same wireless network password, the connection really successful request.

second, the request header error
