## Common causes

- You're trying to activate a manually-collected subscription, which is not possible.

## Common solutions

- Change the billing date of the subscription instead. Set the `next_billed_at` to 30 minutes after the time of your request, then wait 30 minutes for the subscription to become `active`.
- Wait for the subscription to become `active` at the end of the trial period.
