Does Filr Support SMB Encryption?

I'm on Filr 23.4, and users whose home directories are on a windows 2016 file server with SMB Encryption enabled can't open or download files. They get a permission error in the web ui, and the I get the following errors in the famtd.log file on the appliance:

Even if I set 'RejectUnencryptedAccess' to $false on the server, no joy.

If I disable smb encryption completely on that server, everything seems peachy. 

Any one have any insight?
