Why does a domain show a different domain on VestaCP?

Question

Nginx

I linked 4 domains, SSL was successfully installed on all domains. But there is one that has a similar A record with IP.

www.sezam-steklo.ru - the site is displayed correctly. (with http without s)
www.sezam-steklo.ru - redirect to htts
https://sezam-steklo.ru/ - another site is displayed.
https://www.sezam-steklo.ru/ - another site is displayed.
https://sezam-steklo.ru/ - another site is shown.

Actually, because of this problem, SSL Lets Encrypt is not installed. On other domains everything is ideal.

With the rest of the domain everything is OK. wtf? how to set it up?
