SdkClientException: Unable to execute HTTP request: Connection reset - amazon-web-services

Question

I'm trying to upload file to AWS s3 bucket. I'm continuously getting this exception "SdkClientException: Unable to execute HTTP request: Connection reset".
I'm trying to upload by inputstream
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
.withRegion(Regions.US_EAST_2)
.withCredentials(new AWSStaticCredentialsProvider(cred))
.build();
try {
ObjectMetadata metadata = new ObjectMetadata();
metadata.setContentLength(bytesArray.length);
metadata.setContentType("text/csv");
s3Client.putObject(new PutObjectRequest(appConfig.getBucketName(), fileName, inStream, metadata).withCannedAcl(CannedAccessControlList.PublicRead));
}
----
Below is the exception in detail. What could be the reason? My S3 bucket has IAM user with S3 full access policy. Is this issue related to network or any other settings?

Answer 1

I found it is occurring due to the firewall. If you set logging.level.com.amazonaws at DEBUG then it will show SSL handshake failing.

If you are running the application behind a proxy, this may happens. You can set the proxy as,
public static void setProxy() {
System.setProperty("http.proxyHost", "<http-proxy-url>");
System.setProperty("http.proxyPort", "<port>");
System.setProperty("https.proxyHost", "<https-proxy-url>");
System.setProperty("https.proxyPort", "<port>");
}
