You’ve got four certificates which includes both the base domain name as the www prepended hostname: 1, 2, 3, and 4.
But for some reason your most recent certificate only includes the base domain name: https://crt.sh/?id=334454113 And it’s this certificate currently installed on your webserver…
Could you run certbot certificates please and post the output here?
Unfortunately, your nginx is probably configured using the x49.com.br-0001 cert (which doesn’t cover the www subdomain) instead of x49.com.br (which covers both names).
You could try running
fgrep -r .pem /etc/nginx
to find where this has been configured, and then edit it to refer to the other one instead, and then restart nginx.
If that works, you might want to run certbot delete --cert-name x49.com.br-0001 to remove the redundant certificate from your local certificate.
Open /etc/nginx/sites-available/default and delete "-0001" in the two filenames (fullchain.pem and privkey.pem). Restart your nginx afterwards and you should be fine.
