        <ul>
            <li><code>client_max_body_size</code> - Default is 1MB, should be higher</li>
            <li><code>client_body_buffer_size</code> - Buffer size for request body</li>
            <li><code>client_header_timeout</code> - Timeout for client headers</li>
            <li><code>client_body_timeout</code> - Timeout for client body</li>
