Error Requested Range Not Satisfiable about mypyllant HOT 1 OPEN

I was using this call for system in api.get_systems(True,True,True,False) to get statistics.
Now whatever I try to activate the rts data I receive the following response from server:
aiohttp.client_exceptions.ClientResponseError: 404, message='Resource Not Found', url=URL('https://api.vaillant-group.com/service-connected-control/vrc700/v1/rts/xxxxxxxxxxxxxxxxxxxxxxxxxxx/devices')
(I replace the real system identifier).

For the second call: device_data in api.get_data_by_device(system.devices[0])
I receive:
aiohttp.client_exceptions.ClientResponseError: 416, message='Requested Range Not Satisfiable', url=URL('https://api.vaillant-group.com/service-connected-control/end-user-app-api/v1/emf/v2/xxxxxxxxx/devices/xxxxxxxxxxx/buckets?resolution=DAY&operationMode=DOMESTIC_HOT_WATER&energyType=CONSUMED_ELECTRICAL_ENERGY&startDate=2018-11-23T00:00:00Z&endDate=2024-05-21T06:00:58Z')

Unless I add some arguments:
device_data in api.get_data_by_device(system.devices[0],DeviceDataBucketResolution.DAY,date.today(),date.today())
But still no total data.
