This site can’t be reached localhost refused to connect. on empty project

My localhost does not load the page:

http://localhost:8080/ 
This site can’t be reached 
localhost refused to connect.

I have a brand new project and when I run the project I don't get any errors or see any errors but when I try to view using the localhost I see the above error

Here is the detail on my project.

Java version on my machine:

C:\WINDOWS\system32>java -version java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

I have no idea what I'm doing wrong here, and again I have nothing except this class which I run:

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

My POM file:

4.0.0 org.springframework.boot spring-boot-starter-parent 2.4.2 com.example demo 0.0.1-SNAPSHOT demo Demo project for Spring Boot

It looks like spring application didn't start completely and freezes on starting Hikari Pool (last line in your log).

Hikari pool is a database connection pool. This probably means that the DB connection settings in your application.properties are incorrect and connection can't be established.

Can you verify that database is running and responding on the datasource URL you configured?
