PayPal IPN stopped working - curl 35 error

Question

I am using PayPal IPN to ping a PHP listener on my website. It has been working fine for over a year now until today. PayPal is showing the IPN was sent successfully, however if I look at my records it shows it was not processed from my end and if I look in the error log I can see the following error:

[16-Oct-2014 10:54:41] cURL error: [35] error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

Does anyone have any ideas as to why this might happen? What can I do to fix it?

Answer 1

PayPal disabled SSLv3 as a response to the POODLE vunerability. You can read about it here: PayPal Response
