Hi Mike,
we've recently had our AWS toolkit suddenly break. If I try to submit a job through the Relion GUI, the instance never gets launched. If I try to manually launch an instance, it also never starts and is paused indefinitely at "Launching AWS instance ... for user ... "
Has something changed on your end, like an AMI update, etc.?
I can still make and delete EBS volumes from the command line, and I can launch instances from the AWS online console.
Can you think of any way we may have broken your scripts?
Rick
