Please help! I've spent multiple days trying to ssh into my EC2 instance.
I'd been able to do this for the first 24 or so hours. Then as I was adding dependencies to my instance I got booted. Now I'm unable to get back in. At one point my Public DNS changed but I've accounted for this.
My security groups, VPCs, internet gateways, route tables, subnets, firewall, etc. seem to all be in order too.
What is the issue here? Please advise!
