Minio: C# Minio PutBucket Request: A WebException with status NameResolutionFailure was thrown

[Reza-Noei]

I'm working on an Amazon s3 Compatible Object Storage solution (Minio).

I have an Minio server on e.g 192.168.235.143:9000

I have tried to get List of buckets on C# version of Amazon s3 Api. Everything works fine.

When I try to Put a Bucket into this server e.g test1, Visual studio throws this request into an Exception:

Amazon.Runtime.AmazonServiceException:
'A WebException with status NameResolutionFailure was thrown.'

WebException: The remote name could not be resolved: 'test1.192.168.235.143'

here is my code:

AmazonS3Config config = new AmazonS3Config();
config.ServiceURL = "192.168.235.143:9000";
AmazonS3Client client = new AmazonS3Client(AccessKey, SecretKey, config);
PutBucketRequest request = new PutBucketRequest();
request.BucketName = "test1";
// this Line will throws above exception :
client.PutBucket(request);

but ListBuckets works for make me confused:

AmazonS3Client client = new AmazonS3Client(AccessKey, SecretKey, config);
var response = client.ListBuckets();
foreach (S3Bucket b in response.Buckets)
{
MessageBox.Show(string.Format("{0}t{1}", b.BucketName, b.CreationDate));
}

What i have tested to check this Exception's cause:

I have Installed it on a Virtual machine and a local Version for doubly check this issue but it still persists.
I Even Changed Minio port to the port #80
I Even used "play.min.io" but has no difference

I need to use a known interface so we be able to port into another Object Storage Platform e.g Ceph, ....

I have no Idea to get it resolved yet.

Please Help me to find my mistake or a better solution

@Reza-Noei I understand you're using AWS SDK .Net, for that to work with MinIO (in this current setup) you need to enable PathStyle. Here is a sample: https://github.com/minio/cookbook/blob/master/docs/aws-sdk-for-dotnet-with-minio.md
