Common causes

You're trying to grant consent for a subscription before the consent period has started.
The system prevents early consent grants to ensure customers have appropriate time to review subscription terms before renewal.

Wait until after the consent_period.starts_at timestamp before attempting to grant consent.
Check the subscription consent requirement's consent_period.starts_at property to determine when consent can be granted.
