Hi all,

I’ve been trying to add an S3 source from my aws dremio stack, i get this error after opening my bucket:

No AWS Credentials provided by STSCredentialProviderV1 : com.amazonaws.SdkClientException: Unable to execute HTTP request: Connect to [sts.amazonaws.com:80](http://sts.amazonaws.com:80) [[sts.amazonaws.com/54.239.21.217](http://sts.amazonaws.com/54.239.21.217)] failed: Connection refused (Connection refused)

Can you assist?

Have you tried encrypting the connection by checking “Encrypt connection”?

@brianmposi

Can you click on advanced options and try to check “Enable compatibility mode (experimental)” and see if it works

Thanks
