 * Hey Zep,
 * Hope you’re well today 🙂
 * Are you having this issue when using Live PayPal account or a Sandbox one?
 * Also is this a live site or hosted locally?
 * Please advise,
    Bojan

 * Hey again Zep,
 * Can you please check if you have any security plugins on your site that could
   cause this.
 * Aside from that this could be related to your server firewall settings that are
   preventing IPN requests from being sent. You can contact your hosting provider
   with this?
 * Best regards,
    Bojan
