Deploying MeshCentral with Let's Encrypt

[primetecabt]

I have MeshCentral installed on a VPS server running Debian 13 version 1.1.53, using MongoDB as the database, with the following configuration:

{
"$schema": "http://info.meshcentral.com/downloads/meshcentral-config-schema.json",
"settings": {
"cert": "acesso.deskinfocontrol.com.br",
"MongoDb": "mongodb://127.0.0.1:27017/meshcentral",
"WANonly": true,

"redirPort": 80,

}
},

}
},

"letsencrypt": {
    "email": "[email protected]",
    "names": "acesso.deskinfocontrol.com.br",
    "skipChallengeVerification": true,
    "production": true
    }
}

}

However, when loading MeshCentral with the command "node node_modules/meshcentral/ --debug cert" .... I receive the output below, but it seems to be stuck.

Currently, the domain is being handled by Cloudflare's free service, but I've disabled their proxy.

The test performed by Let's Debug is also included:

I would greatly appreciate any help.
