[SSL][Resolved] letsencrypt www not working

it's strange that the cert work on non-www but not www.
When I visit the domain with www, I got this problem :

Your connection is not private

I would like to redirect the www to non-www but not work. Finally I found it related to my A/AAAA record settings: (these IP are fake and for examples)

Hostname     IP Address           TTL
------------------------------------------------------------------------------
                    140.164.10.171                             Default
mail            140.164.10.171                              Default
www           140.164.10.171                             Default
                    2400:8901::f04c:21ff:aee4:f001 Default
mail             2400:8901::f04c:21ff:aee4:f001 Default
www           2400:8901::f04c:21ff:aee4:f001 Default

After I removed the line in red, it works.

If still not work, try to reinstall your domain cert (with www) with certbot such as this command :

sudo certbot --nginx

Example :
