Too long wait mesos aws build

Error detecting OS: Too many retries waiting for SSH to be available. Last error: Maximum number of retries (60) exceeded

Is this an aws limit perhaps or a timing config in Rancher? It would seem the machines get build and then when this error shows up Rancher Terminates them. Doing three at a time as the project suggests. Any ideas?

today getting a different error : exit status 1
Is this also related to the aws server taking too long to initialize?

are you adding hosts to an environment? This would indicate that the server cant ssh into the potential host to provision it. Can you make sure the security group has the right permissions?

solved. its was security group and user name etc
