I can't log in to swagger. Unable to infer base url

Question

Gives the following error. I don't use spring Security tried different versions, rebuilt the project, no idea what the problem is

@Configuration
@EnableSwagger2WebMvc
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.mycompany.trainbooking.controller"))
                .paths(PathSelectors.any())
                .build()
                .apiInfo(apiInfo())
                .host("localhost:8080")
                .pathMapping("/tickets");
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Train Booking API")
                .description("API для управления бронированием билетов на поезд")
                .version("1.0")
                .build();
    }
}

@RestController
@RequestMapping("/tickets")

I wrote path Mapping("/") differently, and generally cleaned

When I look at the sources below I see a project that looks abandoned for 3 years now, right after 3.0.0 was released, with questions on this error not answered. My guess is that setting the baseUrl is required somewhere and I would experiment with the @enableswagger2 or use spring boot without springfox.

springfox-boot-starter 3.0.0 : Unable to infer base url

@EnableSwagger2

public SwaggerUiWebMvcConfigurer(String baseUrl) {
    this.baseUrl = baseUrl;
  }
