[knot-resolver-users] TLS with new created LE certs: invalid argument

Hi, I created new certs with Let's Encrypt and knot-resolver just throws "invalid argument" when starting. The old one work fine, so first I thought it's related that they are wildcard certs now, but also new created certs just for "dns.mydomain.tld" also lead to the error. Any ideas? BR Bjoern
