Hi, I am using uacme, an ACME client with support for RFC 8738 which extends the ACME protocol to allow it to issue certificates for IP addresses. This currently fails with Buypass, throwing the following error:

strophy@X250:~/Code/uacme-cert$ uacme -a https://api.buypass.com/acme/directory -v -c . issue 71.198.220.130

}

Are there any plans to support RFC 8738 at Buypass? Support is already available in pebble, and should be available in boulder and certbot and other ACME tools soon.
