How to force a redirect for all devices?

Question

htaccess

Good afternoon. Please help me figure out the redirect of the site. We bought a certificate, made a redirect from http to https and it seems like everything works, BUT for some reason the redirect does not always work. Either on mobile devices, or in the opera, it’s not necessary once again. Site vmebel24.ru. The redirect was done in .htaccess. Site on ocstore 2.3.
How would I force a redirect for all devices?
My .htaccess
RewriteEngine On
# If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^(.*)$ https://vmebel24.ru/$1 [R=301,L]
RewriteBase /
RewriteRule ^sitemap.xml$ index.php?route=extension/feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=extension/feed/google_base [L]
RewriteRule ^system/download/(.*) index.php?route=error/not_found [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js |css)
RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]
