Issue calling SearchDatastoreSubFolders function on one particular datastore

Hi all,

I am looking for some help in regards to this peculiar issue.  The below script works 100% fine for all of my vcenter's datastores with the exception of one.  It produces the below error stating there are communication issues with the datastore.  The datastore in question is online, accessible and otherwise running fine.

Has anyone run into a similar issue?  The script is fine as it works with all other datastores, perhaps some reconfiguration of the problematic datastore is the solution?

Any help is appreciated.  Thanks in advance.
