Running certbot with --manual-auth-hook true (or cat) renewed my wildcard cert without any challenge/authentication.
My domain is: *.goldstein.rs
I ran this command: sudo certbot renew --manual --preferred-challenges=dns --force-renewal --manual-auth-hook true
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
