Access Server's public IP from itself

Hi I have a computer behind ASG that is running a webserver and I would like to access the websites it is hosting using the public IP and not the private from the server itself.

The NAT rule:
Any -> Any -> Public IP
Destination translation: <internal IP of the server>

I can access it from any other computer on my LAN except the computer itself

Any suggestions?

Thanks

When I ping the public IP from the computer itself the IPS is alerting me that same IP has been detected. Also the public IP is an additional IP
