Problem with direct mandate

Dear support,

we´ve got a problem with SEPA direct mandates.

When the first renewal should´ve been done we got the following error:

"Erneute EPS-Zahlung konnte nicht erstellt werden. The customer (cst_JbR77hmBaH) does not have a valid mandate. Status der Bestellung von Zahlung ausstehend auf Fehlgeschlagen geändert."

In the log it says:

2020-11-30T15:10:48+00:00 DEBUG mollie_wc_gateway_eps: Try to create renewal payment for renewal order 1753
2020-11-30T15:10:48+00:00 DEBUG Mollie_WC_Gateway_AbstractSubscription::restore_mollie_customer_id_and_mandate - Subscription 1732 renewal payment: the subscription doesn't meet the conditions for a mandate restore.

Manual renewal didn´t work. Is there a way to fix the mandate, because the customer isn´t reachable? As this was the first “renewal”, also there is the question what we can do, to prevent this from happening again?

WooCommerce is running on Version 4.6.2, Mollie on Version 5.10.0

Many thanks and best regards
Mae
