Sorry the code is not correct.
You simply need to replace mysqli_error($link) with mysqli_connect_error() for the connection error.
This code

USE yourdatabase;
SHOW GLOBAL VARIABLES LIKE 'PORT';

And

USE yourdatabase;
SHOW GRANTS FOR CURRENT_USER;

the first code shows the global port number, while the second shows your privileges for the user who made the connection.
It’s a sql you can run it in phpmyadmin, mysql etc.
You need to replace the name yourdatabase with the name database you use for WordPress.

Note* make sure the database WordPress user is created with local not with any host.

Multisite Network Administration

While permalinks will continue to work, the main site (i.e. the first one created) will have an extra entry of blog, making your URLs appear like domain.com/blog/YYYY/MM/POSTNAME.

This is by design, in order to prevent collisions with SubFolder installs. Currently there is no easy way to change it, as doing so prevents WordPress from auto-detecting collisions between your main site and any subsites. This will be addressed, and customizable, in a future version of WordPress.

Also note that the blog prefix is not used for static pages which will be accessible directly under the base address, e.g. domain.com/PAGENAME. If you try to create a static page in the first site with the name of another existing site on the network, the page’s permalink will get a suffix (e.g. domain.com/PAGENAME-2). If you create a new site with the slug of an existing static page, the static page will not be reachable anymore. To prevent this, you can add the names of your static pages to the blacklist so that no site with that name can be created.

each configuration is different from hosting A and hosting B.
You must follow the guide of your hosting.
If the main domain and the subdomains are in the center of the language, it is absolutely your hosting will change based on the HTTP_HOST variable from the browser .. (it is not the only way but one of the most used).
You need to ask your host for more information as follows: I have a wordpress multisite with main domain end subdomains, how can I enable cron jobs for the main domain and subdomains?

After you get this answer I write you a php code to do your tests (I want to know if the hosting up is based on HTTP_HOST to distinguish the domains).
I modified the previous post with this post.

wp-cron.php offer three method

// Use global $doing_wp_cron lock otherwise use the GET lock. If no lock, trying grabbing a new lock.
if ( empty( $doing_wp_cron ) ) {
	if ( empty( $_GET['doing_wp_cron'] ) ) {
		// Called from external script/job. Try setting a lock.
		if ( $doing_cron_transient && ( $doing_cron_transient + WP_CRON_LOCK_TIMEOUT > $gmt_time ) ) {
			return;
		}
		$doing_cron_transient = $doing_wp_cron = sprintf( '%.22F', microtime( true ) );
		set_transient( 'doing_cron', $doing_wp_cron );
	} else {
		$doing_wp_cron = $_GET['doing_wp_cron'];
	}
}

Example
wp-cron.php with set variable $doing_wp_cron or
wp-cron.php or
wp-cron.php?doing_wp_cron=1560090633.5487570762634277343750

if the request is without www but you want the redirect for both domains.

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

Hi sorry I was not clear only you know what port to use, if you rely on your hosting ask them how to access.
If everything else is managed by you go to phpmyadmin click your database and then enter this sql
SHOW GLOBAL VARIABLES LIKE 'PORT';
If different from 3306 you have to add it as I said before

I can think of blocking theme updates https://codex.wordpress.org/Editing_wp-config.php , or after backup files and databases, set the default theme.
https://codex.wordpress.org/Network_Admin_Themes_Screen#Default_Theme

Clone your Chameleon with new name add it into define function for default theme.

if(!is_array($cronhooks)){
function var_x_error_log( $objectauto=null,$cronsauto=null ){
ob_start(); // start buffer capture
var_dump( $objectauto,$cronsauto ); // dump the value
$contentsauto = ob_get_contents(); // put the buffer into a variable
ob_end_clean(); // end capture
error_log( $contentsauto."\n",3,dirname(__FILE__).'/test.log'); // log contents of the result of var_dump( $objectauto,$cronsauto )
return $contentsauto;
}
var_x_error_log( $cronhooks,$crons );
break;
}

This shows the error in detail, the first array is $cronhooks (in your case bool false) all the other $crons. 🙂

you cannot directly call the cookie because initially it does not exist you have tried as suggested by me and that your function can also return false?
