HTTPS Subdomain - redirect HTTP to HTTPS

[maricksville]

I recently installed an SSL certificate on a subdomain following the steps at cPanel. Lets just say the domain is example.com and the subdomain is sub.example.com.

1. I updated the userdata file for the subdomain and changed the IP address to the IP I wanted to use
2. I updated the example.com zone file and changed the IP for the A Name for the subdomain to the IP I wanted to use
3. Using domain tools I checked that sub.example.com resolved to the new IP which it does.
4. I then installed an SSL certificate on example.com and then on sub.example.com

When I visit http://sub.example.com I get the default Apache account screen, and when I visit https://sub.example.com I get the cPanel 404 page. If however I enter https://sub.example.com/admin (the location of my admin section) the page loads and I can login.

I thought that this might be a propagation issue however as the subdomain resolves to the IP and I can reach the admin page I suspect it is not a propagation issue and possibly an incorrect zone file.

I can now access the site via HTTPS but HTTP returns 404 errors or the default Apache page.

I have tried htaccess redirect using:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

But this does not redirect sub.example.com/index.php to https://sub.example.com/index.php. Same Apache message as previous.

Using the 301 redirection in cPanel does not redirect either.

Could you check the /var/cpanel/userdata/username/subdomain.domain.com and subdomain.domain.com_SSL files? Ensure the paths are all correct for each file. Ensure the IP is correct for each file.

If it isn't and you revise anything, then make a backup of httpd.conf after fixing the file(s), rebuild httpd.conf and restart Apache:

cp /usr/local/apache/conf/httpd.conf /usr/local/apache/conf/httpd.conf.bak120628
/scripts/rebuildhttpdconf
/etc/init.d/httpd restart

Also, check that the DNS zone is properly setup. You said it was, but doesn't hurt to check it in WHM > DNS Functions > Edit a DNS Zone area.
