New Site Created, but not working

I can create a new “site” just fine, but when I go to it’s dashboard I get a URL NOT FOUND error.

Obviously my config file is setup right, so here’s my access file:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

#RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
#RewriteRule ^(.*)$ https://www.domain.com/$1 [R=301,L]

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

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
