Not getting in the network admin

Hi,
I can access the site with just using wp-admin when logging in. But when going to multisite, it sends me again to a login field which I cant access to the site https://www.domain.com/wp-login.php?redirect_to=http%3A%2F%2Fbcperio.ca%2Fwp-admin%2Fnetwork%2F&reauth=1

But when I type it with this https://www.domain.ca/wp-admin/network/ which gives me this link https://www.domain.ca/wp-login.php?redirect_to=http%3A%2F%2Fwww.domain.ca%2Fwp-admin%2Fnetwork%2F&reauth=1 I could get to access the network admin.
here is my access

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

# END WordPress

and the wp-config.php
/* Multisite */

define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('PATH_CURRENT_SITE', '/');
define('SUBDOMAIN_INSTALL', false);
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

And if I add this to the wp-config.php
define(‘DOMAIN_CURRENT_SITE’, ‘www.domain.ca’);
it gives me a redirect loop.

Site is fine, but wondering why I cant access network when clicking on the network admin, I have to type it to get on..

Any advice..
Cheers
