Wordpress SSL & www rewrites - wordpress

Question

Having an issue with some url rewrites.
I want to redirect all urls to https with no www
Currently I have :
1) Forces https with the (s) - working
http://example.com => https://example.com
2) Forces https with the (s) and removes www - working
http://www.example.com => https://example.com
3) Remove the www from the https with the (s) requests - failing
https://www.example.com => https://example.com
It seems as if it's not even reaching my htaccess code with an ERR_SSL_UNRECOGNIZED_NAME_ALERT
Site might be temporarily down or it may have moved permanently to a new web address.
This is what I have in my htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.example.com$ [NC]
RewriteRule ^(.*)$ https://example.com/$1 [R=301,L]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
</IfModule>
The site is hosted by Host Gator and I contacted support and was told that it's impossible to set this up because the site is built with Wordpress.
That didn't seem like the right answer to me so thought I'd ask here.
Any info appreciated.
Cheers

RewriteCond %{HTTPS} off will not detect HTTPS requests, so you may want to add another rule for HTTPS requests only (with the same/similar conditions), e.g.:
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
RewriteRule ^(.*)$ https://example.com/$1 [R=301,L]
Instead of adding this, you can also simplify everything with an OR condition:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{HTTP_HOST} !^example\.com$ [NC]
RewriteRule ^ https://example.com%{REQUEST_URI} [R=301,L]
</IfModule>
Which means, if HTTPS is null or off OR the domain does not start with example.com, redirect to https://example.com.
Amusing that the support believes that Wordpress somehow prevents .htaccess to be used, but I wonder if your host may have certain .htaccess restrictions, preventing plugins that rely on it (e.g. BulletProof Security) to work properly.
