I am getting this exception when I am storing object in AmazonS3EncryptionClient object. Here is my code

ObjectMetadata objectMetadata = new ObjectMetadata();
objectMetadata.setContentLength(plaintext.length);
                objectMetadata.setSSEAlgorithm(ObjectMetadata.AES_256_SERVER_SIDE_ENCRYPTION); 

    AmazonS3EncryptionClient s3 = new AmazonS3EncryptionClient(credentials,materialProvider).withRegion(Region.getRegion(Regions.US_EAST_1));;

    PutObjectRequest putRequest = new PutObjectRequest(
                        bucket, keyId, new ByteArrayInputStream(plaintext), objectMetadata);
    putRequest.setRequestCredentials(credentials);

    s3.setEndpoint("https://kms.us-east-1.amazonaws.com");

I have the same issue, but in my case the problem was with the proxy, Hhere is how you can set the proxy,

here is an example,

ClientConfiguration config = new ClientConfiguration();
config.setProtocol(Protocol.HTTPS);
config.setProxyHost("YOUR_PROXY_IP");
config.setProxyPort(YOUR_PROXY_PORT);


BasicAWSCredentials creds = new BasicAWSCredentials("YOUR_KEY", "YOUR_SECRET"); 
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
    .withClientConfiguration(config)
    .withRegion(Regions.US_EAST_2)
    .withCredentials(new AWSStaticCredentialsProvider(creds))                   
    .build();

我通过在 Amazon IAM 管理控制台中创建存储桶并为端点获取主机解决了此异常。

I had the same issue and was caused by the usage of proxy because the application was living in the same region as the S3 bucket. For the applications that were deployed in a different region the same code worked fine.

I needed to be able to check whether the application is at the same region before setting the proxy client configuration.
