The ERR_TOO_MANY_REDIRECTS error typically occurs when there's a loop in the redirection process. Let's go through some potential solutions:

Check your site and home URLs:

Make sure that the site and home URLs for your subdirectory site are correctly set in the database. You can check this by accessing your database through phpMyAdmin or a similar tool. Look for the wp_2_options table (assuming site1 is the second site in your network) and check the siteurl and home option values.

Verify SSL settings:

If you're using SSL (https), ensure that all URLs in your configuration are consistently using either http or https, not a mix of both.

Check your wp-config.php file:

Your wp-config.php file looks mostly correct, but let's make a small adjustment:

define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST']);
define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST']);

Obs.: Remove the trailing slash from these definitions.

Adjust your .htaccess file:

Your .htaccess file looks correct for a multisite setup, but let's try a slightly modified version:

# 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

Remember to back up your site before making any significant changes. If you try these steps and still face issues, please provide any new error messages or behaviors you observe, and I'll be happy to help further.
