from the apple discussions:


Apple changed some defaults and suggested to check if there is some
update from any NAS etc vendor to solve that problem at the other side
... , as Apple added the change to protect against the Badlock-Exploits ...

To add back the old defaults:

sudo -s
echo "[default]" > /etc/nsmb.conf
echo signing_required=no >> /etc/nsmb.conf
