Hello, I am obtaining a certificate using dn01 challenge. It is giving dns txt record to update in DNS, once this validation passed it is giving me certificate. As I got my certificate, should I keep the txt record in DNS as it is? or Can I delete that txt record ? . Need some inputs here!
So @JuergenAuer you’re saying if I keep the TXT record , next time I don’t need to generate a new one. I can renew with the help of old one, and can have a chance to automate it? is there any link or documents that helps me to automate renewal certificates with dns challenge.
