Try again later.”after re-start my instance problem is fix. I need to fix that.Need your help

Without essential details about your setup, e.g. OS, installation method etc., my guess is that you have insufficient resources to run Ghost on EC2.

Here you cannot provide me proper details, but for establishing connection to ec2 instance using PuTTY SSH client. To know the full process click here.

I don’t know if you resolved this problem or gave up but I had a similar issue and resolved it by adding swap space. I documented the process here and then I have automated the process further here. I hope this helps.
