Hi guhananth1,

• According to the "Not found' error message, you can check whether "http://localhost:5125/oauth/token" is correct. You need to make sure that you can access "http://localhost:5125", and ensure this path is correct.
• About how to get JWT token,you can refer to this link .You need "Microsoft.AspNetCore.Authentication.JwtBearer" and "System.IdentityModel.Tokens.Jwt". For more detailed configuration you need to check the link I gave above.I tested this link and can get the token value very well.

Below is the code I tested.

        public async Task<IActionResult> IndexAsync()
        {
            AuthenticateResponse result = new AuthenticateResponse();
            string apiUrl = "https://localhost:44399/users/authenticate";
            AuthenticateRequest test = new AuthenticateRequest
            {
                Username = "test",
                Password = "test"
            };
            var json = Newtonsoft.Json.JsonConvert.SerializeObject(test);
            var stringContent = new StringContent(json, System.Text.Encoding.UTF8, "application/json");
            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri(apiUrl);
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
            HttpResponseMessage response = await client.PostAsync(apiUrl, stringContent);
            if (response.IsSuccessStatusCode)
            {
                var data = await response.Content.ReadAsStringAsync();
                result = Newtonsoft.Json.JsonConvert.DeserializeObject<AuthenticateResponse>(data);
            }
            return View();
        }

Here is the result.

Best Regards,
