413 request entity too large HAProxy | Resolved

According to our experts, the “413 Request Entity Too Large” error in HAProxy occurs when the client sends a request with a payload that exceeds the configured maximum request size limit.

HAProxy enforces this limit to prevent excessively large requests from overwhelming the backend servers.

HAProxy by default has a maximum request size limit to ensure system stability and prevent resource exhaustion. This limit is set in the HAProxy configuration with the http-request max-body-size directive.

If a client sends a request with a payload that is more than the configured request size limit, HAProxy rejects the request and responds with the 413 status code.

How to resolve the “413 Request Entity Too Large” error

1. First, we have to increase the request size limit in the HAProxy configuration by locating the parameter in the configuration file.
2. Then, we have to modify the value according to our desired request size.
3. Next, we have to ensure the backend servers can handle the increased request size. Our experts recommend checking the configurations of the backend servers and adjusting their request size limits to match the limit set in HAProxy.
4. However, if we cannot modify the HAProxy configuration or backend server limits, we have to reduce the request size from the client side. This involves optimizing the payload, compressing data, or splitting large requests into smaller ones.
5. Now, we have to restart or reload HAProxy to apply the changes.
