This is the only way it works for me - with !on instead of off and with %{ENV:HTTPS} instead of %{HTTPS}:

  #non-www. http to www. https
  RewriteCond %{ENV:HTTPS} !on
  RewriteCond %{HTTP_HOST} ^(www\.)?yourdomain\.com$
  RewriteRule (.*) https://www.yourdomain.com/$1 [R=301,L]

  #non-www. https to www. https
  RewriteCond %{ENV:HTTPS} on
  RewriteCond %{HTTP_HOST} ^yourdomain\.com$
  RewriteRule (.*) https://www.yourdomain.com/$1 [R=301,L]
