We would need to know what you have in your .htaccess file to redirect. If we know what you have there, you can get suggestions to make it work the way you want.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.example.com [NC]
RewriteRule ^(.*)$ https://example.com/$1 [L,R=301]

I'm sorry its not htaccess, according to the sever type its web.config

i really appreciate that, thank you
I'm a little bit confused for the issue and I'm missing a lot of points to consider in the first message

I'm trying to find a reason why your screenshot does not load after moving the discussion to the IIS Forum. I'll try again to see what has changed.

Finally got something to show here. Sorry for the delay.

But, but, but...

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.example.com [NC]
RewriteRule ^(.*)$ https://example.com/$1 [L,R=301]

That’s Apache, not IIS. Which of the two--the screenshot, or the posted snippet--is actually used on the site? And if Apache, is it in htaccess, in a <Directory> section, or loose in config?

The first thing to make sure of is that the coded canonicalization redirect is actually happening. You can test this easily in your browser by requesting various pages with the “wrong” form of hostname, and checking that you end up on the preferred form.

@lucy24 - The screenshot and the post preceding it told me to move the discussion from the Apache forum to the IIS forum.

Yes, then look at your logs to be sure there are no multiple redirects. When you request https://www.example.com/page.html your logs should show a 301 response and then a 200 response for https://example.com/page.html

There are some old instructions (from 2008) that explain how to redirect: [webmasterworld.com...]
- to paraphrase from that thread:

The way to do that is create a new separate website entry and then on the "Home Directory" tab

Select A redirection to A URL
https://example.com

And tick A permanent redirection for this resource.

I can't tell you whether that is accurate current information, but you should be able to ask the host how to set it up.
