Too many redirects on wp-admin

I am trying to install WP Multisite on my blog https://www.gameplayinside.com. The aim is to create a working subdirectory install of /civilization/

I was able to get Multisite working, however the additional website I added is not working properly.

On my test server I have followed official tutorial and enabled WP multisite:

Step1: Disable all plugins

Then update config:

/* Multisite */
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'www.gameplayinside.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

I also updated htaccess

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

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ wp/$1 [L]
RewriteRule . index.php [L]

# END WordPress

After that I was able to add another website as ‘superadmin’. So I added ‘civilization’. Meaning I now have 2 entries:

https://www.gameplayinside.com
https://www.gameplayinside.com/civilization

The primary website is functioning like it should. However the new website is not:

What I already tried:
Adding

/* https://tommcfarlin.com/resolving-the-wordpress-multisite-redirect-loop/ */
define('ADMIN_COOKIE_PATH', '/');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');

And installing the twentysixteen on the network because the new page displayed a message that it was unable to find the theme folder. This did resolve that message but it did not fix wp-admin.
