[StarCluster] StarCluster newbie question

[Teddy Thomas]

Hi Boris-

The error looks like there’s an issue with making the API call to AWS to
setup the security groups. The name or service not known makes me think
this may be a DNS issue or other connectivity issue on the AWS instance
you’re running. Is the instance in a fully private subnet by chance,
without a route to the Internet?
