Sub Domain not working!

Hi there!
I used 000webhosting for a while and switched to InfinityFree because of the Unlimited Bandwith and Disk Space.(hence the we’re moving screen when going to my website.)
I wanted a sub-domain and when i created a subdomain named it’s just filled with ads!
When using something like it works but only my own domain doesn’t work.
i’m using GoDaddy & Cloudflare.

Sorry for bothering.
