    Ok, I come back with this issue again, its was all this year and i pretty sure it’s from WordFence, when you work with ModSecure and turn off WordFence it’s not showing errors in the log.

    I run check on this IP:
    209.141.45.176

    Belong to these guys:
    https://frantech.ca/

    Now, i develop my cloud and my cPanel by myself, I work with Google Cloud and i don’t think they work with Fran Tech…

    The error on both of my servers, in different locations:
    server.locksmithunit.es
    server.locksmithunit.cat

    It’s come from my websites:
    https://locksmithunit.com

    and 2 in EU:
    https://locksmithunit.es
    https://locksmithunit.cat

    when you activate WordFence on the websites, the same server get errors in nginx log.
    Now, i don’t was call it error (maybe it’s good and this actually reject suspicious request)
    But it’s flooding the Nginx log, and i a little curious why it’s the same error in all the websites and the server:

    Showing last 100 entries from /var/log/nginx/error.log

    Hi @123nadav,

    I’ve had a little time to look into the log information you’ve provided with some of the development team. This looks like an NGINX configuration matter, as the log entries are NGINX reporting that it can’t connect to the a site it’s been set up to proxy. This happens before PHP even runs, so is unlikely to be affected by Wordfence that can’t run at this stage of the request without PHP.

    If you don’t know what azenv[.]net is, check your NGINX configuration to see whether that site or the IP (45.33.51.119) is included anywhere. If NGINX is unintentionally being used as an open proxy, the connection to that IP may just be failing, which is not such a bad thing as you mention FranTech which has been associated with high risk traffic.

    Thanks,

    Peter.

    @wfpeter so i am actually right, Nginx block them (i more suspect in mod_secure2)
    this mod connects to NGINX.

    Ok @wfpeter something wired.

    When i go to WordFence > All Options

    And put Learning mode.
    Its stop and add himself to Word fence:
    https://ibb.co/zfvDh4Q

    is not there now, i delete it and i am now using the “Enable and Protect”

    The same IP…
    What you say? It can be Plugin? Attack?
    If i turn learning mode is move to allow list… maybe it’s good!?!?
    Or it’s attack for sure??

    (@wfpeter)

    Hi @123nadav, thanks for the extra investigation into this.

    For the reason of PHP’s order in running that I mentioned before, that change to Learning Mode being effective certainly seems odd. You could try looking at access logs to see whether requests are being blocked or getting redirected. Do there appear to be multiple requests when this occurs, or only one? Compare that information to log entries from the same IP when Wordfence is not active.

    Thanks,

    Peter.
