As stated in the docs there is a daily maintenance window in the exact online API, and during those times no requests should be made to avoid unexpected behaviour.
Server maintenance. Due to server maintenance the Exact Online server is unavailable. Avoid making API calls between 04:00-04:30 (CET) because maintenance is scheduled during this time slot

proposed fix
Maybe there should be some safe guards in the API calling method that check the current time and intercept the calls made. Of course there should be a way to still force a call.
