I can't figure out how to set up a redirect from http to https

Answer 1

RewriteCond %{REMOTE_HOST} !^xxx\.xxx\.xxx\.xxx - what is this? Tipo so that if you enter by IP was a redirect to the domain?
Try like this:

RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

Or:

RewriteCond %{HTTP_HOST} !^mysite.ru$ [NC]
RewriteRule ^(.*)$ https://mysite.ru/$1 [L,R=301]
