What happens when there are multiple challenges for the same domain?
Stay organized with collections
Save and categorize content based on your preferences.
If there are multiple challenges for the same domain, Google Trust Services will
attempt to validate all of them. If any validation fails, issuance will be
denied.
If you need multiple ACME challenge TXT records, use separate TXT records like:
_acme-challenge.www.example.org. 300 IN TXT "abcdef...uvwxyz"
_acme-challenge.www.example.org. 300 IN TXT "zyxwvu...fedcba"
Don't use a single TXT record with multiple challenges like:
_acme-challenge.www.example.org. 300 IN TXT "abcdef...uvwxyz" "zyxwvu...fedcba"
