called from Blazor client HttpClient.GetJsonAsync returns (with data), but then times out

hope this fix your issue You're probably getting stuck in a deadlock because you are abusing async. You shouldn't be calling .Wait() and .Result, use async code properly.
First make the method async and return a Task:
code :
private async Task load_click()
{
    // snip
}
var users = await Http.GetJsonAsync<UsersPageData>("api/ShowerQ/Users");

Retrieving HttpClient service does not work with Blazor Client

With these it helps I can not retrieve the default HttpClient injected by the server in the Blazor client.
code :
public void ConfigureServices(IServiceCollection services)
{
              services.AddSingleton<MService>(); 


}
@inject IServiceProvider services

@functions {
    WeatherForecast[] forecasts;

    protected override async Task OnInitAsync()
    {
        var client = services.GetRequiredService<HttpClient>();
        forecasts = await client.GetJsonAsync<WeatherForecast[]>("/sample-data/weather.json");
    }
}
IServiceProvider Services = services.BuildServiceProvider();
var client = Services.GetRequiredService<HttpClient>();

Blazor - passing arguments through Http.GetJsonAsync

I wish this help you If you want to send two arguments, you can define a class with two fields for these arguments. This class will automatically be JSON-encoded and sent as a string
You can use the SendJsonAsync method whose signature is displayed below:
code :
  public static async Task<T> SendJsonAsync<T>(this HttpClient httpClient, HttpMethod method, string requestUri, object content)

// And this is how you can use it in your code...
trackList = await Http.SendJsonAsync<Change this to the return type>( HttpMethod.Get, "/api/Lopstat/Tracks", MyObject);   

How Do I Call HttpClient in Service for a Blazor Client-Side App


By : user3056270

seems to work fine You are missing using System.Net.Http; to have access to the class in WeatherService.cs
code :
// WeatherService.cs
using System.Threading.Tasks;
using System.Net.Http; //<-- THIS WAS MISSING

namespace MyBlazorApp.Shared {
    public interface IWeatherService {
        Task<Weather> Get(decimal latitude, decimal longitude);
    }

    public class WeatherService : IWeatherService {
        private HttpClient httpClient;

        public WeatherService(HttpClient httpClient) {
            this.httpClient = httpClient;
        }

        public async Task<Weather> Get(decimal latitude, decimal longitude) {
            // Do stuff
        }

    }
}
