Spring boot with thymeleaf could not resolve view with name

I'm setting a spring boot project with thymeleaf but my view isn't displaying and getting the following error in the browser.

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

Controller:

@Controller
public class MainController {

    @GetMapping("/")
    public String homePage() {
        return "home";
    }
}

application.properties:

spring.thymeleaf.cache=false
spring.thymeleaf.enabled=true
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html

spring.application.name=Bootstrap Spring Boot

I had added thymeleaf feature in my html file, but when it wasn't working I just made it simple html file. My home.html is:

<html>
<head>
<title>Home Page</title>
</head>
<body>
    <h1>Hello !</h1>
    <p>
        Welcome to Our App</span>
    </p>
</body>
</html>

It's a very simple and basic controller. I am not seeing any exception stack trace in the console.

Solution

After a couple of days of effort, I resolved this issue by downgrading spring boot version from 2.1.5 to

<version>2.0.6.RELEASE</version>
