The connection to “domain” is not secure
I use this for my htaccess force-SSL rule on my multisites (actually, on all sites). RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] Not sure, but bet that off is better than !=on .A resource you can use to test htaccess rules is https://htaccess.madewithlove.com/ .
