Redirect to new domain using https Apache - apache

Question

I've got this domain:
www.example.com
And I want to redirect it to
https://www.example2.com
This is what I have in my .htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule (.*)$ https://www.example2.com/$1 [R=301,L]
#Joomla Rules
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php [L]
</IfModule>
If I try from www.example.com the rules are applied it and redirects me, but when I try from example.com it shows me an insecurity error (NET::ERR_CERT_AUTHORITY_INVALID). How can I make it work both ways?
P.S. both domains point to the same IP

Answer 1

Check the below code for redirect one domain to another domain :
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule (.*)$ http://www.example2.com/$1 [R=301,L]
</IfModule>
OR
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?example.com [NC]
RewriteRule ^(.*)$ http://www.example2.com/$1 [R=301,NC,L]
</IfModule>
I hope it's helpful to you.

Answer 2

Turns out I cannot just redirect to an SSL domain if the redirected domain isn't SSL as well, this post gave me the answer.
Nginx HTTPS 301 redirect to another TLD (hosted on same server) without showing SSL warning
Thank you!
