IOSLinkedInAPI: Authorization failed LinkedIn1: Error Domain=LIALinkedInERROR Code=1 "The operation couldn’t be completed. (LIALinkedInERROR error 1.)"

Hi, I am getting the next error:

Authorization failed LinkedIn1: Error Domain=LIALinkedInERROR Code=1 "The operation couldn’t be completed. (LIALinkedInERROR error 1.)"

when I tap a custom build LinkedIn button.

Here is the code that I am using:

#pragma mark Linkedin integration
- (void)suggestionsPopupLinkedInButtonFunction{
    dispatch_async(dispatch_get_main_queue(), ^{
    [_client getAuthorizationCode:^(NSString *code) {
        [_client getAccessToken:code success:^(NSDictionary *accessTokenData) {
            NSString *accessToken = [accessTokenData objectForKey:@"access_token"];
            [self requestMeWithToken:accessToken];
        }                   failure:^(NSError *error) {
            NSLog(@"Quering accessToken failed %@", error);
        }];
    }
                           cancel:^{
        NSLog(@"Authorization was cancelled by user");
    }
                          failure:^(NSError *error) {
        NSLog(@"Authorization failed LinkedIn1: %@", error);
    }];
    });
}

- (void)requestMeWithToken:(NSString *)accessToken {
    [_client GET:[NSString stringWithFormat:@"https://api.linkedin.com/v1/people/~:(skills)?oauth2_access_token=%@&format=json", accessToken] parameters:nil success:^(AFHTTPRequestOperation *operation, NSDictionary *result) {
        NSLog(@"current user %@", result);
        //process the received result and convert it to string
        NSString *skillFinalString = @"";

        for (int countValuesSize = 0; countValuesSize < [[[result objectForKey:@"skills"] objectForKey:@"values"] count]; countValuesSize++) {
            NSString *skillValueString = [[NSString alloc] initWithString:[[[[[result objectForKey:@"skills"] objectForKey:@"values"] objectAtIndex:countValuesSize] objectForKey:@"skill"] objectForKey:@"name"]];
            NSLog(@"skillValueString = %@", skillValueString);
            if (countValuesSize < [[[result objectForKey:@"skills"] objectForKey:@"values"] count] - 1) {

                skillFinalString = [NSString stringWithFormat:@"%@; ",[skillFinalString stringByAppendingString:skillValueString]];

            } else {
                skillFinalString = [skillFinalString stringByAppendingString:skillValueString];
            }

        }
        //send the skillFinalString data to class variable and send them to server when finish/ done button is pressed
        NSLog(@"%@", skillFinalString);
        LinkedInInfo = skillFinalString;
        NSLog(@"%@", skillFinalString);

        // Hide all social network Ui ellements from suggestion page
        [self hideAllSocialPopupElements];

        //save the newlly retrived data to logedinUservCard
        [logedinUservCard setObject:LinkedInInfo atIndexedSubscript:9];
        [logedinUservCard setObject:[NSString stringWithFormat:@""] atIndexedSubscript:1];
        [self updatevCard];

    }        failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"failed to fetch current user %@", error);
    }];
}

- (LIALinkedInHttpClient *)client {
    LIALinkedInApplication *application = [LIALinkedInApplication applicationWithRedirectURL:@"http://www.newrosoft.com/"
                                                                                    clientId:@"77ibz6e8ed8i53"
                                                                                clientSecret:@"jkfPVSmEqGredwXO"
                                                                                       state:@"DCEEFWF45453sdffef424"
                                                                               grantedAccess:@[@"r_fullprofile", @"r_network"]];
    return [LIALinkedInHttpClient clientForApplication:application presentingViewController:nil];
}

and also i declare:

LIALinkedInHttpClient *_client;

witch takes the value:

_client = [self client];

Also I have opened a stack overflow issue.
