Meteor npm get request ECONNRESET

Question

我正在使用以下方法上传到Meteor中的S3存储桶。我收到请求，如果有响应，我将其上传到S3存储桶。我有大约700个这样的网址。我为每个URL执行HTTP GET请求，并尝试上传到S3。主要问题是，在一开始，对于大约150个文件，我得到以下错误：

I20170725-22:22:39.344(2)? An error occured during upload:  { [Error: 
connect ECONNRESET https://pushmetrics.com:443]
I20170725-22:22:39.344(2)?   code: 'ECONNRESET',
I20170725-22:22:39.344(2)?   errno: 'ECONNRESET',
I20170725-22:22:39.345(2)?   syscall: 'connect',
I20170725-22:22:39.345(2)?   address: 'https://pushmetrics.com',
I20170725-22:22:39.345(2)?   port: 443

之后它适用于其他文件。只有前150个网址失败。

uploadToS3: (url, headers, connectionId, itemId, itemName, type) => {
    return new Promise(function(resolve, reject) {
        request.get({
            url: url,
            headers: headers,
            rejectUnauthorized: false,
        }, function(error, response, body) {
            if (error) {  
                reject(error);
            } else {
                // Create S3 service object
                var s3 = new AWS.S3();
                // bucketName var below crates a "folder" for each item
                var bucketName = '/connections/' + connectionId + '/' + type + '/' + itemId + '/';
                var params = {
                    Bucket: Meteor.settings.private.s3.bucket,
                    Key: bucketName + itemName + '.png',
                    Body: body,
                    ContentType: 'image/png',
                    ACL: 'public-read'
                };
                s3.upload(params, function (err, data) {
                    if (err) {
                        console.log(`Error during upload file ${params.Key} to S3: ${err}"`);
                        return res.status(500).send(err)
                    };
                    let s3Url = data.Location;
                    resolve(s3Url)
                });
            }
        });
    });
},

方法uploadToS3由以下异步方法调用：

uploadItemToS3: async (url, headers, connectionId, itemId, itemName, type) => {
    s3Url = await Api.uploadToS3(url, headers, connectionId, itemId, itemName, type);
    return s3Url;
}
