After upgrade to 16.04 caot access Samba share

I use Nautilus to access Weste Digital My Cloud but after upgrading to 16.04 I can't coect. No error message, nothing happens.

I followed the advice found on askubuntu and added the line "client use spnego = no" to my smb.conf file at the top of the global section but no joy.

I also tried re-creating the nautilus bookmark using the ip address of the wdmycloud - no joy there either.
