We have an app deployed to LHR, at 14:20 today we noticed that it is no longer accessible but also disappeared from the dashboard. After redeploying, it is back again.
Please run fly status --all and see if you have “failed” VMs. If you do, run fly vm status <id> and see if that tells you anything. You see messages about a VM exiting with a non-zero code, that means the process crashed.
If you see exit code 0, check and see what it says about health checks.
“Internal” error from our proxy could mean a number of things. You might see that error if your app processes were crashing.
If you run fly logs -i <vm id> you might be able to see why. You may need to install something like Sentry to get better details if the logs don’t tell you much, though.
