Payment problems

Updated: 8 November 2026

What happens if a renewal payment fails and how to change your card.

If a renewal payment fails

The processor may try again and may ask your bank to confirm (3D Secure). Until the payment succeeds, the account moves to Free at once: there is no grace period. When the payment goes through, the plan comes back and a new 30-day period starts on the day of the payment.

What you can check

  1. The card is valid and has enough funds.
  2. Your bank has not blocked online payments or the 3D Secure confirmation.
  3. Your card details are up to date in the customer portal (Settings → Billing → Manage subscription).
