objective-c - ios上传到7牛华南区失败求解？

Question

如图安卓端已成功上传，并开辟空间华南，token是从后台获取的就是传不上去求高手指引
// 华南

    QNConfiguration *config = [QNConfiguration build:^(QNConfigurationBuilder *builder) {
        builder.zone = [QNZone zone2];
        QNUploadManager *upManager = [[QNUploadManager alloc] initWithConfiguration:config];

// params:nil
// checkCrc:NO
// cancellationSignal:nil];

        //        NSString * token = @"从服务端SDK获取";
        //        NSString * key = @"指定七牛服务上的文件名，或nil";
        //        NSString * filePath = @"要上传的文件路径";
        UIImage *image = [UIImage imageNamed:@"tab@3x"];
        NSData *data = UIImagePNGRepresentation(image);
        [upManager putData:data key:nil token:token complete:^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {
            if(info.ok)
            {
                NSLog(@"请求成功");
            }
            else{
                NSLog(@"失败");
                //如果失败，这里可以把info信息上报自己的服务器，便于后面分析上传错误原因
            }
            NSLog(@"info ===== %@", info);
            NSLog(@"resp ===== %@", resp);
        }
                    option:nil];
    
    }];
    

以下为7牛返回内容（错误）
