Personal Video Database

Hello together,

i recently Downloaded the latest version of PVD and installed it on a LOcal PC.
Then i opened the Programm and created a new DB, the DB should be located at my QNAP NAS System.

But when i click on the save Button i get an Error with the Code 401.

Where is the Problem?

Is this a problem with RW-Permissions?
Anyone knows maybe how i have to configure my NAS that this works...
Or is there another issue?

Would be nice if someone could help.

Thanks.
