 * Are you still getting this error message today?
 * If so, can you try clicking the link near the bottom of the Wordfence Options
   page, “Click to test connectivity to the Wordfence API servers”, and post the
   results here? It may have the same result, but there could be other information
   that may help.

 * The problem started a few days ago (I have been running the website for about
   1 month).
 * It also can’t see the location of human users in the live traffic.

 * Yep — the location data is related to this. If it started a few days ago (and
   not yesterday), then it shouldn’t be related to the WordPress 4.3.1 update (the
   certificate list now comes with the WordPress core.)
 * When you said you disabled the check on SSL certificates, you mean the “Enable
   SSL Verification” checkbox on the Wordfence Options page, right? (Just to confirm
   it’s not another method.) It’s odd for that not to have had an effect.
 * It’s possible your host is proxying outbound requests, or doing something else
   unusual. If you tell them that your site needs to connect to noc1.wordfence.com
   by HTTPS, they should be able to test it by another method from the same host.

 * Hi Matt,
 * Thanks for the info. Yes the Enable SSL Verification is unticked. My website 
   is an Amazon Affiliate so I don’t need this certificate enabled anyway. Should
   I ask my host to connect to no1.wordfence.com by HTTPS?

 * I contacted my host and they said that there were too many processes going on,
   and this was probably the problem. They added my site to a whitelist and they
   said that noc1.wordfence.com is not the issue.
 * It looks like a plugin problem. I think i will reinstall wordfence and see if
   this clears up the problem.

 * I deactivated and removed Wordfence. Then tried to reinstall it. Bam!
 * Installing Plugin: Wordfence Security 6.0.17
    Downloading install package from
   [http://downloads.wordpress.org/plugin/wordfence.6.0.17.zip…](http://downloads.wordpress.org/plugin/wordfence.6.0.17.zip…)
 * Download failed. Problem with the SSL CA cert (path? access rights?)
 * Return to Plugin Installer
 * Anyone know how to get past this?

 * Ok, it sounds like the original error may actually be coming from WordPress trying
   to check for core/plugin updates (that would explain why unchecking the SSL verification
   box in Wordfence didn’t help). Wordfence does show errors that other plugins 
   or WP core cause, even if they would normally be hidden, while it is running 
   some of its processes.
 * The same error showing up from plugin installation is definitely from WordPress
   itself.
 * You might need to reinstall WordPress, though trying to reinstall it through 
   the updates menu will probably cause the same error, so you may need to do it
   by FTP.
 * You _might_ be able to just replace this file on your site with a copy from the
   current WordPress version:
    /wp-includes/certificates/ca-bundle.crt
 * You can get a .zip of the latest version of WordPress here:

 * Were you able to get things working again? Since it looks like it’s a WordPress
   core issue and not Wordfence itself, I’m marking this as resolved, but I’m hoping
   you were able to fix it too!
