Synchronization of the central workshared cloud model in Revit cannot be performed. The process fails and this error message appears in Revit:

           Sync With Central

The Revit journal records lines similar to the following:

0:< Failed to upload ModelResourceId(type=HistoryTable, number=0).

   ' 0:<   NOCACHES3 >> Elapsed time to Write All Available Files (current) = 158 milliseconds

   ' 0:< << NOCACHES3 >> WriteServerModelDataTask::writeAllAvailableFiles

   ' 0:< [00002018]DBG_INFO: Some exceptions occurs during canceling uploading tasks!: line 308 of ModelAccessProvider\WriteServerModelDataTask.cpp.

Causes:

The cause is generally an upload failure (with *.s3.amazon.com), usually caused by a network restriction, such as a firewall or proxy.

Solution:
