can't resolve error establishing database connection

Posted August 3, 2020 446 views

I get this error at least twice a week on my wordpress website. I confirmed an attack with “grep xmlrpc /var/log/apache2/access.log” I enabled “sudo a2enconf block-xmlrpc”

And, I even also set up a plugin called Stop XML-RPC Attacks. It was worse in the past but I still get this error, how can I stop it?

For example, I got this error today and I typed “grep xmlrpc /var/log/apache2/access.log” and got nothing.

  • Hi, thanks. It seems like my server ran out of memory and quit. But, how is this possible? I am using the smallest plan but I have around 40-50 visitors a day. As I see, my memory fluctuates around 60%, is this normal?

WordPress is a popular and powerful CMS (content management system) platform. Its popularity can bring unwanted attention in the form of malicious traffic specially targeted at a WordPress site.

Hi @rem3n,

What you can do is actually block access to XMRPC.php file and allow access only to needed IP addresses.

Additionally, you can try and configure fail2ban. It should be able to help incase someone is doing a DDoS.
