[atlas] NTP empty results ('result': [{'x': '*'}])

Hi folks, I am getting some NTP results in the following format: 'result': [{'x': '*'}], Does anyone know waht is this supposed to mean? is it like the measurement did not run? See blob below: {'fw': 5080, 'mver': '2.6.2', 'lts': 20, 'dst_name': '186.155.28.147', 'dst_addr': '186.155.28.147', 'src_addr': '10.10.31.19', 'proto': 'UDP', 'af': 4, 'result': [{'x': '*'}], 'msm_id': 47867316, 'prb_id': 33745, 'timestamp': 1671799154, 'msm_name': 'Ntp', 'from': '85.238.41.3', 'type': 'ntp', 'group_id': 47867316, 'stored_timestamp': 1671799249}] thanks, /giovane
