✅ (solved) dot net cannot send post request to my endpoint

Hey guys, need some help understanding why my dotnet app is not working:

let btn = document.getElementById('submit');
let URL = 'localhost:8080/controller';
document.getElementById('result-value').value = false.toString();


btn.onclick = (e) => {
    let req = new XMLHttpRequest();
    req.open("POST", URL, true);

    req.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

    req.onreadystatechange = function () {
        if (req.readyState == XMLHttpRequest.DONE && req.status == 200) {
            let answer = JSON.parse(req.response);
            if (typeof (answer.access) != 'undefined') {
                document.getElementById('result-value').value = answer.access.toString();
            }
        }
    }
    req.send(JSON.stringify({
        Login: document.getElementById('login').value,
        Password: document.getElementById('pass').value
    }));
};

let btn = document.getElementById('submit');
let URL = 'localhost:8080/controller';
document.getElementById('result-value').value = false.toString();


btn.onclick = (e) => {
    let req = new XMLHttpRequest();
    req.open("POST", URL, true);

    req.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

    req.onreadystatechange = function () {
        if (req.readyState == XMLHttpRequest.DONE && req.status == 200) {
            let answer = JSON.parse(req.response);
            if (typeof (answer.access) != 'undefined') {
                document.getElementById('result-value').value = answer.access.toString();
            }
        }
    }
    req.send(JSON.stringify({
        Login: document.getElementById('login').value,
        Password: document.getElementById('pass').value
    }));
};

I have such js frontend that sends a post request to my 'localhost:8080/controller' I have such coontroller in my dotnet app:

using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;

namespace YourNamespace.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class LoginController : ControllerBase
    {
        private static readonly Dictionary<string, string> Users = new Dictionary<string, string>
        {
            {"admin", "admin"},
            {"dsfsdf", "sdfsdf"}
        };

        [HttpPost]
        public IActionResult Post([FromBody] LoginRequest request)
        {
            if (Users.TryGetValue(request.Login, out var password) && password == request.Password)
            {
                return Ok(new { access = true });
            }

            return Ok(new { access = false });
        }
    }

    public class LoginRequest
    {
        public string Login { get; set; }
        public string Password { get; set; }
    }
}

using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;

namespace YourNamespace.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class LoginController : ControllerBase
    {
        private static readonly Dictionary<string, string> Users = new Dictionary<string, string>
        {
            {"admin", "admin"},

        };

        {
            if (Users.TryGetValue(request.Login, out var password) && password == request.Password)
            {
                return Ok(new { access = true });
