I receive 404 in webhook

Hi.
I have a webhook to update products in my ERP. Webhook sends the data and updates it in my ERP. But in the WooCommerce log a 404 appears and the webhook is set as disabled. Is this normal? I can’t find a solution.
Thank you.

This is my url webhook:

<?php
	define('WP_USE_THEMES', false);
	require('./wp-blog-header.php');
	$movimiento = 26485;
	$value = 55;
	$return = array (
		'id' => $movimiento,
		'can_devol' => $value
	);
	$return_json = json_encode($return);
	global $wp_version;
	$args = array(
		'timeout'     => 5,
		'redirection' => 5,
		'httpversion' => '1.0',
		'user-agent'  => 'WordPress/' . $wp_version . '; ' . home_url(),
		'blocking'    => true,
		'headers'     => array('Content-Type' => 'application/json',),
		'cookies'     => array(),
		'body'        => $return_json,
		'compress'    => false,
		'decompress'  => true,
		'sslverify'   => true,
		'stream'      => false,
		'filename'    => null	
	);
	$response = wp_remote_post( $url, $args);
