Unable to route with an IP in AWS

we are hosting a php forum in AWS EC2... we have a public ip of 52.xx.xx.xx

it works outside our network but not internally...

​

we have a Windows server 2016 DC with DNS pointing to the correct IP...

​

also we have an entry in Cloudflare for external users.

​

when I try to access in our network via IP I get a 403 forbidden

​

but here is the kicker that I dont understand... when I go to C:\Windows\System32\drivers\etc\hosts

​

and put my 53.xx.xx.xx forums.mysite.com

​

it then works internally... why?

​

what should I change or look at? I am lost
