Support » Plugin: Wordfence Security - Firewall & Malware Scan » Cloudflare cookie blocks WF ability to connect back to my site (503 error)

  • Resolved comicref


    I’ve been using WF for a couple of months now. I migrated to a new VPS last week and installed mod_cloudflare to pass original IPs back to WF. Everything’s been working fine until today when I tried to look at live traffic and noticed Live Activity showing as idle. Went to diagnostics and saw the ostensible issue under connectivity. Next to “connecting back to this site,” I got this message:

    wp_remote_post() test back to this server failed! Response was: 503 Service Unavailable<br /> This additional info may help you diagnose the issue. The response headers we received were:<br /> date => Fri, 23 Jun 2017 20:33:24 GMT<br /> content-type => text/html; charset=UTF-8<br /> set-cookie => __cfduid=d43359e1aa57b8959b2ac81a09bcfac231498250004; expires=Sat, 23-Jun-18 20:33:24 GMT; path=/;; HttpOnly<br /> x-frame-options => SAMEORIGIN<br /> refresh => 8;URL=/cdn-cgi/l/chk_jschl?pass=1498250008.055-aq0YHoBKiC<br /> cache-control => no-cache<br /> server => cloudflare-nginx<br /> cf-ray => 373a38dd59495909-DFW<br />

    I’m not an expert, but that looks like a Cloudflare cookie set to expire in one year. I’ve tried clearing my Cloudflare cache and even pausing CF. No dice.

    I did have some connectivity issues before this during a slight traffic spike this morning. I’ve since installed W3 Total Cache to help mitigate that issue. I have no clue if my connectivity issues this morning might have anything to do with this WF issue.

  • No sooner I post this, I see the connectivity issue is gone, but WF still doesn’t show live traffic. Now Wordfence Live Activity seems to be stuck on showing me same alert that it’s blocking a certain IP for exceeding the number of pages not found errors per minute for humans.

    Hi comicref,
    Could you please check that you didn’t block your own server IP address? Also, on the Live Traffic page, check the browser console for any JS errors that might appear there.
