Not able to access grafana URL outside the widows server

I have installed grafana on a windows server, i am able to access the URL http://localhost:3000/ by logging onto the server, but i am not able to access the URL from outside the machine either through IP address or machine name? what could be the reason

Have you opened port 3000 as an Inbound Rule on the grafana host?

Thank you, after creating the inbound rule i am able to access it from outside the server.
