Yesterday I had an app that started giving a lot of these errors
could not make HTTP request to instance: connection error: timed out
My app was running two instances in the sin region. Both of them started giving this error and the health checks were also failing.
I still haven’t been able to figure out the cause, but let’s assume that something went wrong (either fly’s proxy was not able to route or the app was not accepting connections).
My question is, how can I tell fly to create new machines automatically to make sure I have 2 healthy instances (since my scale count was 2). I can see a restart_limit flag but that seems to be for v1 apps.
What is the default behaviour expected to be and how can I do some configuration here. I am using a fly.toml file.
