As the title says I'm having some problems with my https connection, it was working perfectly but now (2 weeks after) I was installing the Jetpack plug-in on my wordpress site when I got an IXR -32300: transport error: http_request_failed SSL certificate problem: unable to get local issuer certificate error.

I went to my website and the https connection was working perfectly (I can still access it) and the certificate details on the browser said that it was still valid:

Certificate description on Safari and Chrome

But openssl s_client -connect tiferrei.com:443 gives:

CONNECTED(00000003)

Some more info:

I'm sorry this probably a super easy and simple question and I tried Google but I couldn't find anything that worked, I even searched throw the WordPress forums.

Thanks in advance, Tiferei

  • Exactly where did you see that error? – Michael Hampton Dec 26 '15 at 21:49
  • Wow that was quick! I saw it when I was reinstalling the Jetpack wordpress plugin, and after install I have to connect it to my wordpress account, this usually leads to a login page in wordpress.com but I got this error right above the "Connect to wordpress" button. – Tiago Ferreira Dec 26 '15 at 21:53
  • OK, so it's Wordpress.com can't connect to you? The first thing I would do is [fix the SSL misconfigurations](https://www.ssllabs.com/ssltest/analyze.html?d=tiferrei.com&hideResults=on) of your site. If you installed Let's Encrypt it should have [configured Apache correctly](https://github.com/letsencrypt/letsencrypt/blob/master/letsencrypt-apache/letsencrypt_apache/options-ssl-apache.conf), but it appears something went wrong there. – Michael Hampton Dec 26 '15 at 21:56
  • At first I also thought it was something specific, maybe I wasn't allowing wordpress on my firewall or something like that, (btw self-hosted with port forwarding) but the I ran that command and I saw that it wasn't just wordpress... – Tiago Ferreira Dec 26 '15 at 21:58
  • Also, I'm a complete beginner on this so how exactly do I apply the suggested improvements? – Tiago Ferreira Dec 26 '15 at 22:00
  • Got the disable SSLv3 one but have no idea how to de the others... – Tiago Ferreira Dec 26 '15 at 22:10
  • Solved the SSL misconfigurations, A+ grade But I keep getting the same error. – Tiago Ferreira Jan 01 '16 at 18:05
