I get this SQL A transport-level error, but not all the time
public static void QueryDB(string query)
    {
        cmd = new SqlCommand();
        cmd.CommandText = query;
        cmd.Connection = MyConn;
        if (dr != null) dr.Dispose();
        dr = cmd.ExecuteReader();
    }

MyConn = new SqlConnection("Data Source=tcp:localhost; Database=EscalationManagementSystem; Integrated Security=true;");
