.htaccess - Remove "www." from url with forceful https

I am using the following in my .htaccess file to force https on any user that is visiting my website without https in the url.

However, if the user visits https://www.mysite.co, I want to be able to remove the www from the request.

Please can you tell me what I need to modify in my .htaccess file in order to remove the www from the url while maintaining the forceful https?

Thanks,

Max.

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://mysite.co/$1 [R,L]

Answer

Do it with 2 rewrites.

RewriteEngine On 

RewriteCond %{HTTPS}  off
RewriteRule ^(.*)$ https://mysite.co/$1 [R,L]

RewriteCond %{HTTPS}  on

RewriteCond %{HTTP_HOST}  ^www\. [NC]
RewriteRule ^(.*)$ https://mysite.co/$1 [R,L]
