Cannot update network due to network admin redirect loop

Hi, I’m running a multisite with a subdirectory. I can access both sites admin dashboard, but on both home dashboards im told to update my network, but this sends me into a redirect loop, and im not able to access the network admin dashboard.

I have feel like i’ve looked in every corner of this forum for answers, and there are alot of topics concerning the same issue, but i have yet to find any solution… So i hope someone can point out the obvious error for me.

Im running wordpress from mydomain.com/wordpress/ but the siteurl i mydomain.com where I use RewriteBase /wordpress/ in .htaccess which is located root folder of the server outside the wordpress install. So the url for site 1 is mydomain.com and site 2 is mydomain.com/two

the url for network admin w/ redirect loop accouring looks like this:
mydomain.com/wordpress/wp-admin/network/

I have a feeling it has something to do with my .htaccess and wp-config.php to do, but not sure at all. my database seems to correspond with my wp-config.php

wp-config.php looks like this:

define ('WPLANG', 'en_US');

define ('FS_METHOD', 'direct');

define('WP_DEBUG', false);

/* Multisite */
define('WP_ALLOW_MULTISITE', true);

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'mydomain.com');
define('PATH_CURRENT_SITE', '/wordpress/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');

//--- disable auto upgrade
define( 'AUTOMATIC_UPDATER_DISABLED', true );

.htaccess looks like this:

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

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [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).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
