In short, even putting WooCommerce’s number of allowable failures to 100 million attempts, the webhooks system simply stops sending POSTs after a while.
additional information, I used 2 themes, Astra and Ocean WP, in Ocean the webhook works for about 1 and a half days, in Astra it is already 1 hour, at most 2 hours, the results were obtained with the native webhooks of WooCommerce and WP Webhooks PRO webhooks.
