I am hosting 5 sites on my server. Using Apache 2.4.56 and PHP 7.4.30.
I am getting comments that the pages sometimes give an error of being unsecure. I have valid SSL for each site.
Refreshing the page will reconnect the SSL properly.
I have the httpd-vhosts.conf redirecting (permanent) to the secure version (HTTPS) for all domains.
What could be causing the intermittent Unsecure Error?
