My domain is:
I ran this command:
certbot certonly --webroot -w /tmp/letsencrypt-auto/ --must-staple -d xn--auauaiaioaeeiauuouuoouuaieieaiuuaoa-o7c04dhamabgauej1vieciu.eu --staple-ocsp --rsa-key-size 4096
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator webroot, Installer None Obtaining a new certificate An unexpected error occurred: The CSR is unacceptable (e.g., due to a short key) :: Error finalizing order :: issuing precertificate: CSR doesn't contain a SAN short enough to fit in CN Please see the logfiles in /var/log/letsencrypt for more details.
The operating system my web server runs on is (include version): Ubuntu 18.04.3
The version of my client is: 0.31.0
Could anyone give me some pointers how I can acquire a certificate for this domain?
