在 IIS 中发布 web 应用程序后出错

Question

No matter what I do I get this error during run-time:

ExecuteReader requires an open and available Connection.

I have verified that this error is thrown with every SQL service access in my app, I've made sure that every time I access the DB, the connection is opened and then closed respectively.

Hare's an example of my DB class Code:

    public void ConexionDB()
    {
        try
        {
            cnx = new SqlConnection();
            cnx.ConnectionString = "Data Source=DESKTOP-GAHK8CT;Initial Catalog=WInventario;Integrated Security=True";
            cnx.Open();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
    }

    public void DELETE_Lineas(int ID)
    {
        try
        {
            ConexionDB();
            SqlCommand cmd = new SqlCommand("spDELETE_Linea", cnx);
            cmd.Connection = cnx;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter("@ID_Linea", ID));
            cmd.ExecuteNonQuery();
            cnx.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
            cnx.Close();
            throw;
        }
    }

My Application Pool Settings

I have also made sure that the folder that contains has all the permissions with all the available users (Full access).

I'm not sure what else I can check to make it work.

Change -> Data Source=DESKTOP-GAHK8CT to Data Source=localhost
