Paypal IPN：证书验证失败

Question

Since yesterday I'm unable to receive paypal ipn notifications. I've check the log file and the error is:

[24-Mar-2015 13:48:44] cURL error: [60] SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Any thoughts ?

Answer 1

It seems the certificate wasn't valid anymore.

I followed the code comments on the paypal ipn listener sample and downloaded a new certificate from http://curl.haxx.se/docs/caextract.html ( HTTPS from github: ca-bundle.crt ) and replaced the old one. Problem solved.

I hope it helps others.

Answer 2

我已经通过运行 sudo update-ca-certificates 在 Ubuntu 中更新根证书来修复它
