How to redirect from www to https?

Question

htaccess

It is not possible to make a redirect, the site is not accessible at all via the www protocol, and when I uncommented the lines in htaccess, nothing has changed, i.e. redirect is not happening

Не удается получить доступ к сайту Не удалось найти IP-адрес сервера .
Выполните диагностику сети в Windows.
DNS_PROBE_FINISHED_NXDOMAIN

#редирект с www на без www
#RewriteCond %{HTTP_HOST} .
#RewriteCond %{HTTP_HOST} !^ [NC]
#RewriteRule (.*) /$1 [R=301,L]

What is the problem and where is the error
