Ssl server certificate does NOT include an ID which matches

Bonsoir, 

J'avance dans la sécurisation de mon site installé sur un Raspberry et connecté à une Freebox. Quelques infos :

• J'ai un nom de domaine (jean-dupont.fr)
• une adresse ip fixe
• le serveur (raspberry) a l'adresse suivante : 192.168.1 245
• gestion des ports (Freebox):  créé pour le port 80. J'ai supprimé momentanément celui pour le port 443 car le site n'est pas bien sécurisé. 
• j'ai créé un certificat avec Certbot et activé le https mais j'obtiens un message d'erreur.(error.log)

[Sat Feb 21 18:59:44.934656 2026] [ssl:warn] [pid 1525:tid 1525] AH01909: jean.dupont.fr:443:0 server certificate does NOT include an ID which matches the server name

Je pense que l'erreur se trouve dans le fichier /etc/apache2/sites-available/wordpress.conf car je m'y perds quelque peu malgré tout ce que j'ai pu lire.

/etc/apache2/sites-available/wordpress.conf

Qui aurait une solution ?
