PayPal IPN not working

On Joomla 3.9, membership 2.16 (latest). Paypal IPN is not working, after a subscription is done (and paid), it never changes to active, it stays in pending.

The website is under HTTPS, I have turned on the HTTPS flag in Joomla (some extension do not play nice if HTTPS and this flag off). Tested with production PayPal (no sandbox).

Please advise.

As a comment, after paying and accepting the subscription. I do not see any IPN callback from Paypal in my HTTP(s) log. However, I do get the subscription emails from PayPal (payee and payer). My guess is the IPN URL is built wrongly, where may I see it?

Hi Luis

IPN URL does is not built wrong. I would say that there is something on your server blocks the IPN message and it causes the issue. More information, please see membershipprodoc.joomservices.com/troubl...-ipn-troubleshooting

You can access to this page www.paypal.com/cgi-bin/webscr?cmd=_display-ipns-history , find the IPN message related to your test transaction, check the HTTP code of that message to see what's it and then check it further (For example, if it's 403, then it's blocked)
