Can't use Spaces via Amazon S3 SDK

I’m trying to perform a PUT operation towards Spaces using AWS S3 Java SDK, but I keep getting the same error.

Here’s the definition of the client:

    public AmazonS3 spaces() {
        BasicAWSCredentials credentials = new BasicAWSCredentials(...);
        return AmazonS3ClientBuilder.standard().
                withCredentials(new AWSStaticCredentialsProvider(credentials)).
                withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("", "ams3")).

Here’s usage:

spaces.putObject("bucketname", fullPath, tempFile);

And the error is: Bad request (Service: Amazon S3; Status Code: 400; Error Code: 400 Bad request; Request ID: null; S3 Extended Request ID: null)

SDK version:


I tried to replace AwsClientBuilder.EndpointConfiguration("", "ams3") with AwsClientBuilder.EndpointConfiguration("", "ams3"), but it also didn’t work.

And when I try to GET the file, I surprisingly get a different error: null (Service: Amazon S3; Status Code: 403; Error Code: SignatureDoesNotMatch; Request ID: ...; S3 Extended Request ID: ...)

Although I’m pretty sure that I’ve specified key and secret correctly: I double-checked it.


I found that if I listObject for the bucket before putObject, it works. I have been trying to get pre-signed url to upload all day. I am giving up on this. This product is incomplete and/or super buggy. Its not s3 compatible as they claim.

I am facing the same issue with AWS SDK: 1.11.528

(surprisingly after almost one and half years this is still not resolved)

Maybe a better strategy is not to claim DO spaces are S3 compatible.

For me it is working fine in Java:

	private static final String DO_ACCESS_KEY = "some_access_key";
	private static final String DO_SECRET_KEY = "some_secret_key";
	private static final String BUCKET_ENDPOINT = "";
	private static final String BUCKET_REGION = "fra1";
	private static final String BUCKET_NAME = "my-bucket-name";

	public String uploadImageToStorage(byte[] byteimage) {
		AWSCredentialsProvider awscp = new AWSStaticCredentialsProvider(
				new BasicAWSCredentials(DO_ACCESS_KEY, DO_SECRET_KEY));

		AmazonS3 space = AmazonS3ClientBuilder
						new AwsClientBuilder.EndpointConfiguration(BUCKET_ENDPOINT, BUCKET_REGION))

		InputStream is = new ByteArrayInputStream(byteimage);

		ObjectMetadata om = new ObjectMetadata();

		String filepath = "images/users/test/testfile.jpg";
		space.putObject(BUCKET_NAME, filepath, is, om);

		return space.getUrl(BUCKET_NAME, filepath).toString();

I know that the question is old but I faced the same issue and RESOLVED it. In my case, the problem was on the wrong date. The date was set up a few days in the future and I had the issue. After I put the correct date/time everything works fine :-)

I am facing the same problem, Did anyone resolve this or Digital Ocean is not sure about the solution?
