What redirects does BitrixVM create?

Question

1C-Bitrix

Good afternoon. A question from the category of nonsense, but with a seemingly simple experiment, difficulties arose.
In general, I work mainly with 1C-Bitrix. And on a cloud server in the bitrixVM environment, I create versions of sites for development, plus there is also an organization CRM and phpmyadmin installed there to manage MySQL. And I decided to deploy Wordpress on the cover of all this - not only for fun, but also to master it, and for a site on the main domain containing only links to subdomains, heavy Bitrix is ​​not needed. But 100MB wordpress is quite normal.
But with the standard .htaccess file, which works fine on any hosting

# BEGIN WordPress
# Директивы (строки) между `BEGIN WordPress` и `END WordPress`
# созданы автоматически и подлежат изменению только через фильтры WordPress.
# Сделанные вручную изменения между этими маркерами будут перезаписаны.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

But in the BitrixVM environment, it creates an endless redirect.
Why? maybe someone knows.
