My domain does not load in some countries cloudflare

I own a Minecraft Network, what happens is that my domain is bought at godaddy but I transferred the DNS to cloudflare, my problem is that

mc.playshar.com does not load for some countries and for others if I think the problem is cloudflare because since I changed it it stopped loading for several countries

Sorry for the issues.

What do you mean by “does not load”? Do your players see any error message?
