Question about renewal certificate with dns challenge

[JuergenAuer]

Hi @iAmoric

@iAmoric

For the renewal, do I need to set a new TXT record each time or can I reuse the same ?

you need a new txt record. Every order has a challenge, a challenge has a token, there is a hash value computed, this is the dns-txt-entry.

New order -> new Challenge -> new token -> new dns-entry.
