InstanceProfileCredentialsProvider Unable to load credentials from service endpoint

[arodriguez150]

Hi all! I'm using the aws Java sdk with version 1.11.153.

When using the InstanceProfileCredentialsProvider.getCredentials() in an EC2 instance. I'm getting the following error:

com.amazonaws.SdkClientException: Unable to load credentials from service endpoint

I have already confirmed that the instance has a role attached to it.

Also I have tried to do a request like curl http://169.254.169.254/latest/meta-data/iam/security-credentials/myRole and it successfully retrieves the role credentials.

I have already tried upgrading and downgrading the aws sdk version, but nothing seems to solve this issue. Can I get some help?

Thanks!
