Why is my mobile app's API returning 500 errors?
A 500 Internal Server Error means the server failed to handle the request — an unhandled exception, a timeout, a dependency outage. In a mobile app these are easy to miss: the user sees a spinner or a generic 'something went wrong,' and the failure never reaches your analytics unless you instrumented that exact call.
How Drengr helps
Drengr captures every failing endpoint automatically — url, status, error class, count, share of traffic — so the 500 spike is on your dashboard the moment it starts, with zero per-call instrumentation.
