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…
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:
https://wordpress.org/download/
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!
