Lightsail instance inaccessible.

Question

I was working on building something in FastAPI, dinking around with changing responses, when I got disconnected. Since then, the server has been completely inaccessible, and I have no idea why. It doesn't respond to ping, cant connect through SSH, nothing. I've rebooted, stopped/started, and it's like it's there but dead.

Metrics just shows it idling, and I was able to take a snapshot, but I'm not sure what I can even do with the snapshot. I've checked other posts, and I don't really have any idea what went wrong. I wasn't messing around with the firewall or anything that should have blocked my access.

Hi, @Alex Jordan

Unfortunately, Lightsail has limited troubleshooting possibilities as per the following documentation:

You need to export to EC2 for troubleshooting.  
If you can't connect after exporting to EC2, try standard EC2 troubleshooting, such as using EC2Rescue.

> you might need to migrate the Lightsail server to EC2 for troubleshooting further. This is because troubleshooting options are limited in Lightsail as it is for simpler workloads.
