ios - POST with AFNetworking, error code -1001 -

i want post json message send server. don't have access server know working , set return success/failure message when message gets through. server requires app id , password connect

i using afnetworking this. here code i'm using:

nsurl* pushserverurl = [nsurl urlwithstring: @"http://myserverurl.com/"]; afhttpclient* networkinstance = [[afhttpclient alloc] initwithbaseurl: pushserverurl];  nsdictionary *parameters =[nsdictionary dictionarywithobjectsandkeys:                            @"myappid", @"app_id", @"mypassword", @"password", nil];  nsdictionary *params =[nsdictionary dictionarywithobjectsandkeys:                        parameters, @"user", nil];  [networkinstance postpath: @"users/login.json"                parameters: params                   success:^  (afhttprequestoperation *operation, id jsonresponse) {     nslog (@"success"); }                   failure:^ (afhttprequestoperation *operation, nserror *error) {     nslog(@"failed"); }]; 

it fails error code -1001.

the nserror has 4 keys in user info

nserrorfailingurlstringkey value @"http://myserverurl.com/,  nserrorfailingurlkey value <not objective-c object>,  nslocalizeddescription value "the request timed out" nsunderlyingerror , value has no string. 

any idea might doing wrong?

try line of code. can find response coming server or else, actual problem is?

[networkinstance postpath: @"users/login.json"            parameters: params               success:^(afhttprequestoperation *operation, id jsonresponse) {   nslog (@"success"); }               failure:^(afhttprequestoperation *operation, nserror *error) {   nslog(@" error - statistics file upload failed: \"%@\"", [request error]); }];
