Strange canonical URLs problem - help

Strange canonical URLs problem
When I type https://www.mysite.com, https:// mysite.com, http://www.mysite.com or https:// mysite.com into my browsers I see this https://www. mysite.com/ Yes, it’s ok.
But Siteliner accessed the site using both https://www. mysite.com/ and https:// mysite.com/. Siteliner received the same content, but different HTTP codes: 200 and 301 respectively.
Seositechecker suggests putting this code in my .htaccess file to fix stuff.
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
My current code is;
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.mysite.com/$1 [R,L]
Do you have any idea on that issue, please?
Thank you.

You will need to setup .htaccess redirection to either the www or non-www website, depending on how you've installed OpenCart. You can use the .htaccess codes you've pasted above, but some minor changes will be needed to have it point to the correct website. Alternatively, you can use the below.

Thank you, MarketInSG.
Please take a look at this code;
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule (.*) https://www.%{HTTP_HOST}/$1 [R=301]
RewriteRule ^(.*)$ https://www.mysite.com/$1 [R,L]
What's wrong there?

You have 2 rewrite rules and I would suggest trying MarketinSG suggested rules. You can put a # before each line of your existing rules to temporarily disable them while you try the new rules.

MarketInSG's code works. A lot of thanks!

Different tools show the different results. How is it possible?
For example, Siteliner still accessed my site using both https://www. and https:// . Siteliner received the same content, but different HTTP codes: 200 and 301 respectively.

It must be "example.com" to "www.example.com" and then that gets redirected to "https:www.example.com".
What's the code? Suggest please.

The correct way to also be compatible with HSTS would be to redirect to https then to www. Try the code below. Notice the E=HTTPS flag, which ensures that only https requests are redirected to www.

How do you test your sites for URL Canonicalization Issues, please?
Google and these tools didn’t find canonicalization problems with my site:
SeoSiteCheckup,
Seoreviewtools,
seoprofiler,
coderseo.
However, varvy.com/tools/redirects shows this.

I just check manually using the web browsers network inspect tool. You could do it all in one step using something like the code below. However some security scanners (such as https://observatory.mozilla.org/) will flag this up as being a redirect to a different host, preventing HSTS for being set for the domain. https://infosec.mozilla.org/guidelines/ ... directions

OK. Thank you for your help, guys.
