I ran this command:./certbot-auto certonly --standalone
It produced this output: sexychip.com: Non-ASCII domain names not supported. To issue for an
Internationalized Domain Name, use Punycode.
Maybe have sex letter in the my domain, but site content not about sex, it’s site sale underwear
Help me, Please!
@stevenzhu, do you happen to understand how this happens? If you run hexdump -d and type an ASCII domain name in using the Chinese input method, do you see some other Unicode values in the output like a byte order mark or something?
