Why I can't access the endpoint I've set up on my @RestController

I've recently started learning Spring and wanted to exercise a bit. I've created a simple spring boot application, so far it contains only 1 controller with single @GetMapping, but when I try to test it in my browser I only get Whitelabel error. Could someone hint me in the right direction?

Controller:

package com.calculate.calories.web.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.time.Duration;
import java.time.temporal.ChronoUnit;

@RestController
public class RecipeController {

    @GetMapping("/recipe")
    public String getRecipes() {
        HttpRequest request = HttpRequest.newBuilder(URI.create("https://api.aniagotuje.pl/client/posts/search?categories=ciasta-i-torty&diets=&occasions=&tags=&page=0&sort=publish,desc"))
                .GET()
                .timeout(Duration.of(10, ChronoUnit.SECONDS))
                .build();

        HttpClient client = HttpClient.newBuilder().connectTimeout(Duration.of(15, ChronoUnit.SECONDS)).build();
        try {
            HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
            return response.body();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
        return "e";
    }
}

Main:

package com.calculate.calories.start;


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

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class SlimChefApplication {

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