Nginx default upload size

The default maximum file size for uploads in Nginx is 2 MB. Users will receive an error 413 – Request Entity Too Large Error and Solution when uploading a file larger than this limit and you didn't think about setting it when configuring your server.

You can easily raise it with the client_max_body_size directive, e.g.

server {
    # ...
    client_max_body_size 512M;
}
