I recently updated my plugin from 1.44 to 1.49.1 and instances spin up, don't connect, and then don't terminate. If I wasn't looking at aws this would've cost me a lot of money (had over 100 instances running doing nothing).
Everything was working for months before updating. I have an agent.jar that sits in /home/ubuntu. The log from one of the instances is below. If I had to guess I'd say that the issue is that the host is null. Also I don't know what /tmp/remoting.jar is.
Testing the connection and Checking the AMI both succeed.
I have a subnet ID for VPC set correctly.
