Fail to operate SyncFolderHierarchy to archivemsgfolderroot - exchangewebservices

Question

Approximately after 2/22 one of my archive mailbox SyncFolderHierarchy started to encounter this error, but remains work fine.
Is is possible to indicate server failure or some critical server update?
Thanks for help, request, response and headers are enclosed.
