Running .NET6 SwaggerApi on a raspberrypi – Debian

i am trying to run a .Net6 Entity Framework API on my raspberrypi.

After following the Microsoft Docs and running the application, i cannot access swaggerui or API.

There are no errors poping up in console when i try to access the page via http://localhost:5000/

The webbrowser just returns a 401 Error.

Following Code:

Program.cs:

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDbContext<programContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("Context") ?? throw new InvalidOperationException("Connection string 'Context' not found.")));


builder.Services.AddControllers();
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();


var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseHttpsRedirection();
}
app.UseSwagger();
app.UseSwaggerUI();

app.UseAuthentication();
app.UseAuthorization();

app.MapControllers();

app.Run();

appsettings.json:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "programApiContext": "Server=(localdb)\mssqllocaldb;Database=programApi.Data;Trusted_Connection=True;MultipleActiveResultSets=true",
    "programContext": "Server=(localdb)\mssqllocaldb;Database=programApi.Data;Trusted_Connection=True;MultipleActiveResultSets=true"
  }

    After launch your application follow bellow link to get swagger

    https://localhost:5000/swagger/index.html

    Check your launchSettings.json

        "development": {
    "commandName": "Project",
    "dotnetRunMessages": true,
    "launchBrowser": true,
    "launchUrl": "swagger",
    "applicationUrl": "https://localhost:5000",
    "environmentVariables": {
      "ASPNETCORE_ENVIRONMENT": "development"
    }
  }

    To retrieve the Swagger document you need to use its full path. From the Get started with Swashbuckle and ASP.NET Core docs:

    Launch the app and navigate to https://localhost:/swagger/v1/swagger.json. The generated document describing the endpoints appears as shown in OpenAPI specification (openapi.json).

    The Swagger UI can be found at https://localhost:/swagger. Explore the API via Swagger UI and incorporate it in other programs.

    You have to use extra code to display the UI at the root

    To serve the Swagger UI at the app’s root (https://localhost:/), set the RoutePrefix property to an empty string:

    app.UseSwaggerUI(options =>
{
    options.SwaggerEndpoint("/swagger/v1/swagger.json", "v1");
    options.RoutePrefix = string.Empty;
});
