使用AmazonS3客户端调用listBuckets时遭遇Unable to execute HTTP request错误的求助

我有一个Java 17应用，现在想连接NetApp站点上托管的S3存储容器，目前只是想先验证连接是否正常，执行一个简单的listBuckets调用，但一直没搞明白问题出在哪，也不知道该怎么往下推进。

我已经完成了这些准备工作：

• 在NetApp站点上创建了对应的存储桶
• 生成了访问密钥（包含Access Key和Secret Key）

下面是我目前的代码（其实这已经是我查资料、问AI后尝试的方案之一了）：

// Set up your AWS credentials  
String accessKey = "The Access Key I created in NetApp";
String secretKey = "The Secret Key I created in NetApp";

// Set up your S3 endpoint configuration
String endpoint = "https://cee-sgaadm.bhinc.gov";  //This is the base url of the NetApp interface
String region = "us-east-1";

// Create an AWS credentials provider
BasicAWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
AWSStaticCredentialsProvider credentialsProvider = new AWSStaticCredentialsProvider(credentials);

// Create an endpoint configuration for the S3-compatible storage service
AwsClientBuilder.EndpointConfiguration endpointConfiguration = new AwsClientBuilder.EndpointConfiguration(endpoint, region);


// Create an Amazon S3 client with the specified endpoint configuration
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
            .withEndpointConfiguration(endpointConfiguration)
            .withCredentials(credentialsProvider)
            .build();

// You can now use your S3 client to perform operations
System.out.println("S3 client setup successfully.");


// Here's where it dies with a Unable to execute HTTP request: Connection reset error
s3Client.listBuckets();

现在的问题是，代码执行到listBuckets()调用时就失败了，报错信息是“Unable to execute HTTP request: Connection reset”。我现在有点摸不着头脑，不知道到底是哪里出了问题，有没有大佬能给点建议？

非常感谢！
