What causes the error (13)Permission denied: Couldn't read /var/www/SERVERUSER/.htaccess, closing connection or Yandex Bot tricks?

Question

Apache HTTP Server

Periodically, a strange Yandex Bot visits sites hosted on a certain server and the following errors appear in the logs:
[warn] [client 5.255.253.36] (13)Permission denied: Couldn't read /var/www/SERVERUSER/.htaccess, closing connection.
But the root of the site has a path: /var/www/SERVERUSER/data/www/SITE.RU
There are no such errors on other servers with other sites, so the thought arose that the problem was in Apache on this server. What would your friends recommend? Where to dig? Why does the request for .htaccess go to the parent folder of the SERVERUSER user, and not the site (there is .htaccess in the root folder of the site)?
