Swagger .NETCORE can't read json

I’m having a trouble with swagger in .netcore. I’ve tried everything and nothing. I saw another similar questions, but nothing works for me. Running my webapi app with swagger, always returns “Can’t read swagger JSON from http://localhost:5000/api/swagger/v1/swagger.json”.

My codes:

public void ConfigureServices(IServiceCollection services)
    {
        // Add framework services.
        services.AddApplicationInsightsTelemetry(Configuration);
        services.AddCors(options => options.AddPolicy("AllowAll", p => p.AllowAnyOrigin()
                                                                  .AllowAnyMethod()
                                                                   .AllowAnyHeader()));
        services.AddMvc();
        services.AddSwaggerGen();

        services.ConfigureSwaggerGen(options =>
        {
            var info = new Info
            {
                Version = "v1",
                Title = "Web API Multiprodutos",
                Description = "Web API Multiprodutos",
                Contact = new Contact { Name = "Marcos Monte", Url = "www.arrowbus.com.br" }
            };

            options.SingleApiVersion(info);

            string caminhoAplicacao = AppContext.BaseDirectory;
            string nomeAplicacao =
                PlatformServices.Default.Application.ApplicationName;
            string caminhoXmlDoc =
                Path.Combine(caminhoAplicacao, $"{nomeAplicacao}.xml");

            options.IncludeXmlComments(caminhoXmlDoc);
            options.IgnoreObsoleteProperties();
            options.IgnoreObsoleteActions();
            options.DescribeAllEnumsAsStrings();
        });

        services.AddTransient<IServicoSimulacao, ServicoSimulacao>();

        services.AddTransient<IAplicacaoLocalidade, AplicacaoEndereco>();
    }

  public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug();

            app.UseApplicationInsightsRequestTelemetry();
            app.UseApplicationInsightsExceptionTelemetry();

            app.UseCors(builder =>
            {
                builder.AllowAnyOrigin();
                builder.AllowAnyMethod();
                builder.AllowAnyHeader();
            });

            app.UseCors("AllowAll");

            app.UseMvc();
            app.UseMvcWithDefaultRoute();

            app.UseSwagger((httpRequest, swaggerDoc) =>
            {
                swaggerDoc.Host = httpRequest.Host.Value;
            });

            app.UseSwaggerUi(swaggerUrl: Configuration["AppSettings:VirtualDirectory"] + "/swagger/v1/swagger.json", baseRoute: "swagger/ui");
        }

Try this app.UseSwagger(c => { c.RouteTemplate = "api/swagger/{documentName}/swagger.json"; }); app.UseSwaggerUI(c => { c.SwaggerEndpoint("v1/swagger.json", "Some API"); c.RoutePrefix = "api/swagger"; });

This should work.

For anyone experiencing this issue, please ensure you have the latest version of Swashbuckle.AspNetCore - v2.5.0 at the time of writing. If you’ve pulled that down and still experience this issue, let me know and I’ll re-open the ticket.
