DNS-based challange for verification of LetsEncrypt/SSL-certs?

Issuance Tech

Ok, found out that the correct arg is actually “–preferred-challanges” and using a command:

   `/letsencrypt-auto certonly --agree-tos --renew-by-default --manual --preferred-challenges=dns -d mydns.domain1.tld`

I was able to generate a DNS-challange:

    Please deploy a DNS TXT record under the name
    _acme-challenge.mydns.domain1.tld with the following value:
    JHPIuUHGBkadaodaiweirfblaabvlaabadasasajqxU

which then should be added to server DNS-record as a TXT record, with a very shor TTL.
