Windows network shares no longer work, after upgrade to 3.04.17

after the upgrade to firmware 3.04.17 in can’t connect to my NAS (Network Share) It keeps saying invalid user or password

I have restet the hub,clear the Network Name Cache and media Library but nothing works.

When i roll back to firmware 2.07.17 than the network share is ok.

Can someone help me?

What password do you use to log in? Usually it should be the same admin password for the NAS.
