Can't access the External IP on GCP

Question

I've deployed my java application on VM instance. I'm able to access it with EXTERNALIP:8080 and i can access it with my domain "www.domain.com:8080". I've configured to tomcat server to port 80 so that i can access with EXTERNALIP. But my site is refusing to connet to that server. And the tcp:80 port is set to ingres 0.0.0.0/0 it is pointing to internal ip. i'm not finding a solution to point it to the external ip. When i try to run with my external ip i'm getting message like..

This site can’t be reached
EXTERNALIP refused to connect.
