Wordpress website stops working for a particular IP after updating a page

Weirdest problem ever. I use wordpress (last version) for my website and I use WP-bakery page builder. It has worked without problems for years. All my plugins are updated to the latest version, except WP bakery page builder because i'm not paying for it.

Today, i decided to update the website, and I go to the contact page of my website and change 1 word in the page and click "update". The website ends up showing a "timeout" and the website stopped working.

"This site can’t be reached.  Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_TIMED_OUT"

In opera the error is DNS_PROBE_FINISHED_NXDOMAIN

Then I tried with a VPN and the website works, so I try to update the page again and "timeout" again and the website is down

Then I changed the VPN ip again and my website is working on that new IP. I try to change a blog post, no problem, I add new pages with the testimonial plugin and no problem, then, thinking that everything is ok, i go to the contact page again and i change 1 word and boom... time out and the website is dead for that IP

Now I run out of VPNs to test and I can't access my website anymore, but this problem is very strange.

I tried https://www.isitdownrightnow.com/ and that website says that my site is up, but i can't access it anymore due to this change that produced the same awful result 3 or 4 times.

Who knows about this mysterious issue and a potential solution?

Solution

  • I don't know why it happened, but I discovered that a rule of modsecurity blocked my IP whenever I attempted to update my page... Seems to be a security thing with wordpress to avoid attacks... This shows up in the server log.

    To solve it I removed the rule for my website... which may cause some security issues, but who cares about security.

    But I don't know where this blocking comes from...
