AAC Does anybody know how can I edit login message?

[endziu2222]

Above screen is not message when my server is /closeserver.
I do not know where to find this because it only appears when I put wrong password in. Is it possible to modify this message in client 13.20?

        if (g_game().getGameState() == GAME_STATE_CLOSED && !player->hasFlag(PlayerFlags_t::CanAlwaysLogin)) {
            g_game().removePlayerUniqueLogin(player);
            disconnectClient("Server is currently closed.\nPlease try again later.");
            return;
or not this one:

    if (g_game().getGameState() == GAME_STATE_MAINTAIN) {
        disconnectClient("Gameworld is under maintenance. Please re-connect in a while.");
        return;
    }
        }
