There are a few ways you could try to fix or mitigate the problem. We're going to present one of those ways in this article.
By using IP + "Host" HTTP header, you can instruct EasyCron to bypass CloudFlare. Proceed as follows:
For example, if your cron job URL is https://www.example.com, the IP of it is 188.8.131.52. You should add https://184.108.40.206 as cron job URL, and in the "HTTP" tab -> "HTTP headers" field, add Host: www.example.com.
In this way, EasyCron will use your IP (and the domain name) to connect to your website directly, without resolving your domain name to a CloudFlare IP and connect to that IP.
