Forum Linux.débutant Dehydrated & nginx

Bonsoir à tous,

Sous debian buster, je suis passé d'apache2 à nginx recemment.

Seul les "sites-enable" ont été configuré dans nginx.

En lançant la commande dehydrated -c, j'obtiens l'erreur suivante,

ERROR: Challenge is invalid! (returned: invalid) (result: {
  "type": "http-01",
  "status": "invalid",
  "error": {
    "type": "urn:ietf:params:acme:error:unauthorized",
    "detail": "Invalid response from http://mondomain.org/.well-known/acme-challenge/DbPVEoeJr57COMyGR4n5Ok60KC-xfHrUyEzKI124FM8 [XX.XX.XXX.XXX]: \"\u003chtml\u003e\\r\\n\u003chead\u003e\u003ctitle\u003e404 Not Found\u003c/title\u003e\u003c/head\u003e\\r\\n\u003cbody bgcolor=\\\"white\\\"\u003e\\r\\n\u003ccenter\u003e\u003ch1\u003e404 Not Found\u003c/h1\u003e\u003c/center\u003e\\r\\n\u003chr\u003e\u003ccenter\u003e\"",

  },

  "validationRecord": [

      "hostname": "mondomain.org",
      "port": "80",
      "addressesResolved": [
        "XX.XX.XXX.XXX"
      ],
      "addressUsed": "XX.XX.XXX.XXX"
    }
  ]
})

Dans le site-enable, la paragraphe ci-contre devrait me permettre de revalider mon certificat.

    location .well-known/ {
        allow all;
    }

Voici ce que les erreurs de nginx me donnent,
