I am new to Web API. I have written an ASP.NET Core Web API in VS 2022 to communicate with my SQL Server database.

This is my code:

using cd.Data;
using cd.ModelsCd;
using Microsoft.AspNetCore.JsonPatch;
using Microsoft.AspNetCore.Mvc;
using Microsoft.EntityFrameworkCore;

namespace cd.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class CdsController : ControllerBase
    {
        private readonly cdContext _context;

        public CdsController(cdContext context)
        {
            _context = context;
        }

        // GET: api/Cds
        [HttpGet]
        public async Task<ActionResult<IEnumerable<Cd>>> GetCd()
        {
            return await _context.Cd.ToListAsync();
        }

        // GET: api/Cds/5
        [HttpGet("{id}")]
        public async Task<ActionResult<Cd>> GetCd(int id)
        {
            var cd = await _context.Cd.FindAsync(id);

            if (cd == null)
            {
                return NotFound();
            }

            return cd;
        }
}

The code I used to get info is:

static async Task LectureAsync2()
{
    client.BaseAddress = new Uri("http://WebApiCd:7134/");

    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    try
    {
        // get 1 CD
        Console.WriteLine("GET 1 Cd");
        fich Cds1 = null;
        HttpResponseMessage response = await client.GetAsync("http://webapicd:7134/api/Cds/11");

        if (response.IsSuccessStatusCode)
        {
            Cds1 = await response.Content.ReadAsAsync<fich>();
        }

        Console.WriteLine(Cds1.CdNom);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
    }

    Console.ReadLine();
}

I have tried to use it with VS 2022 in a Windows console app => ok, in Windows .NET MAUI => ok, in VSD 2022 .NET MAUI Android emulator or Samsung s21 connected to my PC, the result is a .NET connection failure.

Network config is ok, because I have entered in the Samsung web browser http://webapicd:7134/api/Cds/11 and I get a good response.

Can you, please, indicate what I am doing wrong in Android?

Thanks in advance.
