ssh connection to amazon EC2 instance is timed out

Question

I'm facing an issue where ssh connection to amazon EC2 can not be made. In my case I want to ssh to one of my EC2 instances on aws from Bamboo's local agent. Both are inside the same VPC. I can ssh to my EC2, if I'm logged into Bamboo's local agent. But, I want to achieve the same using ssh task in Bamboo. It tried for 2 minutes and gives me an error - "Can not connect to the host".  What could be the problem here?

Thank you so much for your response.

The problem got resolved by updating the inbound rules in the security group for my Amazon EC2. I added a rule for ssh (port-22). I'm still wondering how was I able to ssh from the bamboo's local agent earlier when the ssh rule wasn't there in the security group.

Hi @Paridhi.Jain

I would try to isolate the problem by checking what is different between you connecting from the agent manually and Bamboo doing it with an SSH task.

* Would you mind trying to connect with EC2 but at this time using a script task?
* Is the remote agent running with the same user you were when connecting to the EC2 instance?
* Is the remote agent able to resolve the hostname used?
* Can you share the build log lines related to this error?
