How to handle an invalid DNS-Challenge

When an challenge become invalid because one of the dns servers was not yet updates,
is there any way to retry the challenge ? Else after such an error the validation is blocked.
Would it be an good idea to use TLSA for validation if an acount/cert key is allowed by the domain owner ?

No. You can't do anything to fix an invalid authorization.

You need to make a new authorization, with a new challenge value, and set the DNS records again. :slightly_frowning_face:

Hi, this raise the next question

  1. Now the Authorization is expired. And there is no newAuthz in
    https://acme-staging-v02.api.letsencrypt.org/directory
  2. The newOrder return only an order with an expired Challenge.
    So what should i do ?
