I presume you’re using `fly logs -a <app-name>`?

If so, it only streams logs (from an app’s stdout/stderr, _I think_) in real-time and doesn’t normally show historical logs.

Strange, because this isn’t true at least for the apps I’ve deployed…

You can, alternatively, deploy a Fly app that stores logs in a local _Loki_ instance ([ref](https://community.fly.io/t/streaming-app-logs-from-one-fly-app-to-another-for-analysis/6676/2)), or streams it out to a sink supported by _Vector_ ([ref](https://community.fly.io/t/fly-logs-to-papertrail-logdna/2476/12)). I doubt that these would capture the logs you otherwise _don’t_ see in the `fly logs` output.
