    Hello,
    We get the following error when Wordfence tries to connect to his server and compare the server files with the local files:

    Scan terminated with error: We received an error response when trying to contact the Wordfence scanning servers. The HTTP status code was [502] and the curl error number was [0]

    Does anybody know what the problem could be? I can’t figure it out.

    Thank you.

  • Thanks for posting this!

    I noticed this earlier, verified it from 2 of my sites, and have escalated to Mark. I’ll update the thread and let everyone know when I find something out.

    Can you try and see if a scan works now?

    Thanks!

    Dear Support
    I got the same issue on 2 different hosting companies today. Both scans finished with the error 502.

    I have checked the error logs (see below).
    The line 82 in /plugins/wordfence/lib/wfAPI.php is calling a function getURL with several parameters, one being WordFence server https://noc1.wordfence.com/ but it returns 502 (bad gateway).
    I have checked directly in the browser https://noc1.wordfence.com/ which returns an error for missing arguments (OK to me), but https://noc1.wordfence.com/ only returns the error 502 (Bad Gateway), which would mean that your server is over loaded.
    Can you please confirm?

    Hi Dominique,

    My apologies, were were completing a systems upgrade this evening which lead to a temporary outage. It should be working fine now. Please let us know if it’s not.

    Thanks.

    Mark.

    Dear Mark

    I have another question related to WordPress hosted with a LiteSpeed V6.6 version. It is the 1st time that I have such an environment.

    I have received the email explaining what to be changed in the .htaccess :

    RewriteEngine On
RewriteBase /

    RewriteRule .* – [E=noabort:1]

    RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

    I am not at ease with .htaccess this is why I am using Bullet Proof Security. It is possible to introduce custom code and I have introduced this one:

    # CUSTOM CODE WP REWRITE LOOP START - Your Custom htaccess code will be created here with AutoMagic
# WP REWRITE LOOP START
RewriteEngine On
RewriteBase /

    RewriteRule .* – [E=noabort:1]

    RewriteRule ^index\.php$ - [L]

    Unfortunately WordFence does still not complete the job and hangs.
    Could you tell me what is wrong?

    Thank you in advance!
    Kind regards,
    Dominique

    I’m getting the error code 502 on several of my sites this afternoon. Seems more server work is being done. Thanks for the post / clarification.

    Due to a storm, we had a brief outage that lasted 19 minutes. All systems have been up and running for some time now, but let us know if you still have trouble. Please make a new post in this forum instead of replying here, if so. Thanks!

    Good afternoon

    In all my sites by scanning error:

    =======
