Short answer: Your server’s being a diva.
Long answer: http error 413 means the server’s like "nah, too big." For Nginx, it’s `client_max_body_size`. For Apache, `LimitRequestBody`. For PHP, those `upload_max_filesize` things.
Fun fact: If you’re using Docker, the config might be hidden in some obscure compose file. Been there.
Tools like `curl -v` can help debug if the server’s *actually* getting your request or just blocking it outright.
