The EziDebitUtil.GetPayments is a process that run every morning. It runs 10 times. This is once of every one of the 10 previous days.
This error log would be an unexpected response from EziDebit. We can assume that this is a temporary issue with their servers and that it would be rectified shortly.
As the routine goes back over the last 10 days each morning, anything missed today will be picked up and corrected tomorrow morning.
If this still causes you concern, please contact EziDebit Support and provide them with the approximate date/time. Perhaps also ask to sign up to their service interruption emails.
