520 CloudFlare error on WordPress login page?

If you are seeing a 520 error issued by CloudFlare when you try to login to your WordPress admin panel i.e. https://www.example.com/wp-login.php that is likely because you are refreshing the page too often or too many devices are trying to load the page at the same time. As LittleBizzy implements brute force protection rules for our customers, that means that the wp-login.php can only be loaded one time per second per IP address. So, simply click the “try again” button in the top right corner that CloudFlare offers you, and it should work fine. The 520 error from CloudFlare means “we don’t know why, but this page is not loading” but in fact it IS loading… just not more than 1x/second per IP address. This is for your own protection, to keep bots or hackers from rapidly attempting to login to your website using hundreds of usernames and passwords and then overloading your server or MySQL database.
