Why am I receiving 520 status codes from my app?
Your app may have crashed while trying to receive an upload or return a response larger than it has been configured to manage.
Why are there multiple 408 errors in App Platform's runtime logs?

Multiple 408 errors are often caused by your app sending health checks with very short timeouts to App Platform. They typically don’t affect the functionality of the app.
Some apps, especially PHP apps, send health checks that time out before App Platform responds, and this causes the 408 error. You can’t prevent the 408 errors from appearing in the runtime logs because you can’t filter or suppress the health checks.

Your team balance may be past due. Pay your balance to lift restrictions on actions you can take on the platform.
Why does my app not restart when it fails a health check?
If an app’s health check fails, the app currently does not restart. This is because App Platform does not currently support liveness probes. An app only automatically restarts if the app crashes or if its disk or RAM usage exceeds the its limits.
