In the file 000-default.conf (folder site enabled) I have those lines:

RewriteCond %{SERVER_NAME} =test.org
RewriteRule ^ https://www.%1%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

For example, my website works on this address https://www.test.org/ and in the WordPress general settings I have the same address as the main website address: https://www.test.org/

Checking all redirection scenario, I saw that left small issue - from this URL https://test.org/ don`t work the redirect here: https://www.test.org/

I use this code:

RewriteEngine on
RewriteCond %{SERVERNAME} =www.test.org [OR]
RewriteCond %{SERVERNAME} =test.org
RewriteRule ^ https://www.%1%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

So I checked all redirect scenario:

http://www.test.org/ - redirect here https://www.test.org/
http://test.org/ - redirect here https://www.test.org/
https://test.org/ - dont redirect here https://www.test.org/
https://www.test.org/ - is ok
So as you see this URL: https://test.org/ dont redirect here: https://www.test.org/

Also actually I don`t know related it to this code or not, but also I use the special redirection plugin called “Redirection” for WordPress - I set-upped 301 redirects from the / - main page to absolutely another website.

And interesting thing - when I delete this redirect via redirection plugin all seems that works well and all redirection scenario works well, but when I use the redirection plugin only this one scenario:

https://test.org/ - don`t redirect here https://www.test.org/ - it directly begins to redirect to the another my website.

So when i using the redirection plugin from the / main page to another website all those redirects scenario works well except only one:

http://www.test.org/ - redirect here https://www.test.org/ and them to the another website

http://test.org/ - redirect here https://www.test.org/ and them to the another website

https://test.org/ - don`t redirect here https://www.test.org/ but directly redirect to another website

Tell please why it is happening and how to fix this issue?

Many thanks.
