Synchronize Error

[SeanRedar]

I used create_replica to successfully create a replica between to GISs but cannot get the subsequent sync using the sync_replicated_items.  Traceback shows an "HTTP Error 498" which eludes to the service URL not being passed a token.  There is a subsequent error but that appears to be related to the first.  Both GISs are AGOL based and am using the current API on my ArcPro install, v1.5. 

Traceback (most recent call last):

During handling of the above exception, another exception occurred:
