I'm getting a problem when trying to synchronize offline data with ArcGIS Runtime:
ArcGIS Data Store encountered too many problems; however, the standby machine 'machine_name' will not proceed with failover due to validation check failures.
and also:
ArcGIS Data Store has detected an issue with Machine: machine_name.
On server there is a Portal for ArcGIS and Data Store to hosting data. GlobalId added, data versioned and archiving.
Portal working just fine. Portal version 10.5
