Redirect from www not working?

Question

Nginx

2 domains on 1 ip are connected to the server. First, the domain conditionally w.ru, then o.ru. I managed to redirect from http to https on both domains. when you go to www.o.ru , the redirect goes to https://w.ru.
I set up nginx in every way according to all the manuals that are in Google, for a redirect. But nothing can be done, even when I completely delete everything that belongs to the w.ru domain in nginx, the redirect from www.o.ru goes to it.
