Hello, i'm not sure if this is the right place for this question. We have a problem with a WordPress plugin which uses PayPal IPN requests to implement the payment process. Unfortunately it seems to be that the requests are never reaching our server. It will try to request 8 times and end up without any status code. Also in the server log files the requests are not listed. It's an Ubuntu 18.04. with plesk installed. I've tried a lot: - Disabling Firewall - Disabling Fail2Ban - Disabling Nginx redirects Nothing helps. On another server, which is from the same hoster, the requests arrive. Could it be a problem on the PayPal side? Greetings, Lucas
