How to get logged in user id in any sub domain,when I was login in network admin

Hello All,
I have multisite with latest wp version.

I would like to get logged in user’s id, in any of my sub domain, when I was logged in network.

I know many phase like :
get_current_user_id();

$current_user = wp_get_current_user();
echo $current_user_id = $current_user->ID;

but that all are get a zero/blank, when I was use in my sub domain.

I am super admin with all access of admin/network
