Describe the bug

Within issue #1459 a fix was created for the http-challenge only. The DNS challenge command does not use the --config parameter which references the letsencrypt.ini file. I can confirm that adding the --preferred-chain = "ISRG Root X1" directly within the requestLetsEncryptSslWithDnsChallenge method does the trick. Don't know if the same directive would be necessary for the renew command though.
