Favicon went missing :D

I contacted domain.com support and they told me “You have to remove 172.67.144.49 IP in cloudfare server”

Can somebody help me with that?

What’s the issue here? Favicon not loading? What’s your domain name?
Do you have some Firewall Rules which unintentionally block loading the resource and showing it to the end-user / visitor of your Website?
Does it actually and physically exist on the origin host / server?
