I have VPS. blocking mean they don't setting proper setting. I having this problem long time. I asked them PHO-FPM childran set 5 before. After I complain they change to 10. After they change I had more than 300 to 500 visitors per day. Now again my visitors back to 100 to 150 now. I think they change to 5 now. They have to speak to me if I have to change server upgrade or what is the problem. I spent lots of money for advertisement in Facebook you tube. Now all waste until I found that 15k visitors requesting from Cloudflare. That's why I want to change my server to different company.
