I have issues running my asp.net core 3.1 web api on a remote server after publishing it. The API is working well on my PC but when I publish it, all API end points are returning error 404. My swagger documentation page swagger/index.html is also returning the same error.
Below is the Program.cs code
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
}
My Startup cs file is as follows
public class Startup
{
private readonly IWebHostEnvironment _env;
private readonly IConfiguration _configuration;
//public static IMvcBuilder ConfigureApiBehaviorOptions(this IMvcBuilder builder, Action<ApiBehaviorOptions> setupAction);
public Startup(IWebHostEnvironment env, IConfiguration configuration)
{
_env = env;
_configuration = configuration;
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
