Why Springfox-swagger2 user interface tells me "Unable to print base url".

Question

Why does the springfox-swagger2 user interface tell me which is not possible Unable to infer base url.As far as I know, I am using the typical spring loaded Swagger configuration.

As you can see in the screenshot, the swagger-fox URL that supports the user interface is example.com/api . NOTE. I get the standard Whitelabel Error PageSpring Whitelabel Error Pagewhen navigating to : https: // localhost: 9600 / api / v2 / api-docs / . I suspect this is the root of the problem? I see no errors in the fact that Spring did not load springfox-swagger2and therefore I do not know why this does not work.

@EnableSwagger2
@EnableWebMvc
@ComponentScan(basePackages = {"com.company.project"})
public class SwaggerConfig
{
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(Predicates.not(RequestHandlerSelectors.basePackage("org.springframework.boot")))
                .apis(Predicates.not(RequestHandlerSelectors.basePackage("org.springframework.cloud")))
                .apis(Predicates.not(RequestHandlerSelectors.basePackage("org.springframework.data.rest.webmvc")))
                .paths(PathSelectors.any())
                .build();
    }
}
