I'm also having the same issue. In my case, I'm building a suscription system using Joomla and everything was working fine last weekend, but suddenly the IPN stopped working. For some reason PayPal isn't sending any notification to the system, so the orders get stuck on a Pending Status. I contacted the extension's developers for support and they told me following: Thank you for providing us with access. I've tried to do one test payment at your site using paypal and then I checked paypal sandbox account. Ipn URL is set correctly but on IPN history page not showing any ipn it means paypal didn't send any ipn on that URL. see here: https://monosnap.com/direct/7PacyOuKys6WJrdIlnHDVO0Jv60o7p Whenever a payment notification is sent on ipn url it will show in paypal ipn history page whether it's success, or failed. As it's not showing then need to contact to paypal support team. PayPlans will update the subscription status when receive ipn from paypal as ipn not coming that's why the subscription is not updated. You need to contact to paypal support team about this issue, that Payment notification are not sending on ipn. you can share the video link also which i shared with you. Also update us with the response you will get from paypal support team.
