Adding domains

Hi i wanted to get a custom domain for my aternos server but freenom is not working is there any alternatives that will work?, Have a nice day!

Oh btw i need something that is atleast free and user friendly right now, im using cloudflare domains but its hard to set up.

Oh, i have been using freenom before i used CloudFlare. But the it keeps saying that the order has been canceled because of a technical issue and many people has been Experiencing it, i tried typing random letters but nothing won't work. I tried searching other alterantives for freenom but all of them is paid i really need help on this one since i'm a beginner and don't know how to use this domain thing i just need a custom ip so people can connect to the server...

heres the error after i got the domain from freenom
