当从postgresql数据库中获取数据时，面临图像中显示的错误。

[HttpPost]
public ActionResult UserLogin(LoginModel login)
{
    string connString = "HOST = 172.18.0.202; PORT = 5432; DATABASE = MRSAC; PASSWORD = MRSACGEOTAG@123; USER ID = MRSACGEOTAG";

    try
    {
        NpgsqlConnection con = new NpgsqlConnection(connString);
        string query = "select  userlogin,password from \"MRSACGEOTAG\".\"loginadminmaster\" where userlogin ='" + login.userlogin + "' and password ='" + login.password + "'  ";
        DataTable dt = new DataTable();
        NpgsqlCommand cmd = new NpgsqlCommand(query, con);
        con.Open();
        NpgsqlDataAdapter ngpsqlAdp = new NpgsqlDataAdapter(cmd);
        NpgsqlDataReader dr;
        dr = cmd.ExecuteReader();

        if (dr.Read())
        {
            con.Close();
            //return View("Create");
            FormsAuthentication.SetAuthCookie(login.userlogin,false);
            return RedirectToAction("Dashboard", "Dashboard");
        }
        else
        {
            con.Close();
            ViewBag.errmsg = "Not valid Credentials";
        }

        return View("LandingPage");
    }
    catch (Exception ex)
    {
        throw (ex);
    }
}

我遇到了这个错误：System.Reflection. TargetExceptionException：'Exception has been thrown by the target of an invocation'。
InnerException：InvalidOperationException：此实现不是Windows平台FIPS验证的加密算法的一部分。
我试着更新PostgreSQL版本，但它面临着同样的问题。
