Hi, @Laurent888. I did see that the SSL certificate for this site only covered the www subdomain. I was able to extend the SSL certificate by clicking the “Renew certificate” button under Site Name > Settings > Domain management > HTTPS.
The apex/root domain URL ( https://laurenttram.com) no longer shows a certificate error because the certificate now does include this domain as well.
If there are other questions or concerns, please let us know.
