Hi Justin,

I'm working with Carlos in a project. We already found the problem, it seems
that when there is another instance (other project) running with another
keypair and in the same AWS account, our instance (with starcluster) with
our keypair has problems, I think that it is a conflict problem... Well, we
decide to take down the other instance (not ours), and it solved...
