413 Payload Too Large (HTTP Status Code 413)

HTTP 413 error, also known as “Payload Too Large,” indicates that the request entity sent by the client exceeds the maximum size limit allowed by the server. This situation typically occurs when uploading large files or submitting a significant amount of data. The server may close the connection or return a Retry-After header field.

Solutions

Reduce Request Body Size: If uploading a file, try compressing the file or reducing its size.
Increase Server Configuration Limits: As a server administrator, you can modify server settings to increase the maximum allowed request body size. For example, in Nginx, you can set the client_max_body_size parameter in the nginx.conf file.
Send Data in Batches: If the request body contains a lot of data, consider sending it in smaller batches.
Use multipart/form-data Format: When uploading files, ensure to use the multipart/form-data format, which is the standard way to handle file uploads.
Check Client Code: Ensure that the client code correctly sets the Content-Length request header and that its value matches the actual request body size.
Use a Proxy Server: If a proxy server is used, check its configuration to see if it also restricts the request body size.
Contact Technical Support: If the above methods do not resolve the issue, it may be necessary to contact the website’s technical support or development team for assistance.

Note: Additionally, if requests are sent through a proxy server or firewall, they may also impose limits on request body size, so you should contact an administrator for adjustments.

When dealing with a 413 error, also note that if it is a GET request, a long URI due to too many parameters can be resolved by adjusting the client_header_buffer_size and large_client_header_buffers parameters.
