HTTP 413 Content Too Large: the request content exceeds an accepted limit
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
HTTP 413 means the server refuses to process the request because its content is larger than it is willing or able to process.
Safety first
Stop and check this first
- Do not remove upload limits globally. They protect memory, storage and availability; raise only the intended route with bounded validation.
Safe checks you can perform
- Measure the transmitted and decoded size
- Identify the first layer returning 413
- Use the documented upload mechanism
Leave these tasks to a qualified professional
- Do not attempt this professional task: Align size limits end to end
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Align size limits end to end
What they doSet deliberate limits across edge, proxy and application, document the effective minimum and monitor rejected sizes.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Measure the transmitted and decoded size
Compare the actual request body, multipart overhead and documented decompressed limit without uploading private data elsewhere.
Do not remove upload limits globally. They protect memory, storage and availability; raise only the intended route with bounded validation.

Identify the first layer returning 413
Use response headers and request IDs to distinguish CDN, proxy, framework and application limits.
Do not remove upload limits globally. They protect memory, storage and availability; raise only the intended route with bounded validation.

Use the documented upload mechanism
Reduce the permitted content, split it only when supported, or use a direct/chunked upload endpoint defined by the service.
Do not remove upload limits globally. They protect memory, storage and availability; raise only the intended route with bounded validation.

What it means
The rejecting server can close the request or connection. The limit may belong to an edge, proxy, framework or application rather than the final storage system.

Symptoms and causes
Probable causes · in order
- The payload exceeds a configured request limitConfirmed
File, JSON, multipart or decompressed content can be larger than the receiving layer allows.
Evidence: RFC 9110 section 15.5.14 - 413 Content Too Large · IANA Hypertext Transfer Protocol Status Code Registry
- Different layers enforce different maximum sizesPossible
The edge or reverse proxy can reject a body before the application-specific upload limit is evaluated.

Does 413 still appear after these checks?
Answer a few questions to narrow down the likely cause and the safest next action. Guidance only - it never replaces a professional.
