How do I check the IPN flow to see where the problem is? I noticed in IPN history in paypal, for the good ones before it stopped working, it had http 200 as the response code. For all the ones that are failing (has worked in 5 days) there's nothing there for the response code. Does that mean PayPal can't reach my server? if so, what could cause that issue? Was working for for 5 months, didn't change anything. My hoster says they are http 1.1/tls 1.2 compliant thanks
