Bonjour à tous,
Depuis 2 jours, j’ai un message CRON m’anoncant que mon sous.domaine documents.mondomaine.tld ne peut pas renouveler le certificat Let’s Encrypt.
Le renouvellement pour tous les autres sous-domainees - 4 avec applications (paheko 2 fois, roundcube, opensondages) + 2 sans application se renouvellent correctement.
Sur le domaine en question, Collabora 26 est installé et fontionne correctement.
Je pallie cette erreur en installant un certificat aut serveur DNS chez OVH ne rapporte aucune erreur particulière.
