When validate order using DNS challenge (
dns-01) we can got error about incorrect validation, because not all DNS servers got new information about TXT records (e.g. validation process on ACME is failed with error).
After this SSL certificate can not issued, because API returned invalid status on challenge validation (cached version) during unknown time (normal it’s 1 hour, but lately is’s large then 3 hour.).
How correct to handle this errors, e.g. validation errors. Retry after a certain time? Or another actions?
