How to Find Why a Website Returns an Error Only for Large Requests

Large requests can exceed body limits, timeouts, memory, proxy buffers, or application constraints that normal pages never hit.

Checks to make

Reproduce with a safe test payload, record size and duration, and inspect proxy and application logs for the first failing layer. Compare upload limits and timeout settings across the request path, then adjust the narrowest limit supported by capacity and security needs.

When to get help
