ACME v2 order is still pending, with all challenges in valid state

The ACME V2 documentation says that when the challenges are valid, the order will change to the ready state. All the domains that I have remain in pending, although all the challenges are in valid state, can you explain to me why this happens?

My domain is: alebarcelona.com

I ran this command: /acme/order/XXXXX/XXXXX

It produced this output:
{
“status”: “pending”,
“expires”: “2018-04-02T14:28:00Z”,
“identifiers”: [
{
“type”: “dns”,
“value”: “*.alebarcelona.com”
}
],
“authorizations”: [
https://acme-v02.api.letsencrypt.org/acme/authz/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
],
“finalize”: “https://acme-v02.api.letsencrypt.org/acme/finalize/XXXXXX/XXXXXXX
}

The "ready" state is unfortunately not supported yet.
