Failed to connect via SMB protocol.

Hi. I've tried to upload files via SMB protocol, but I've gotten the error:

TeamCity server and Build Agent are installed on the same server. TeamCity Professional 2017.1.4 (build 47070).

Build Step settings:

I've checked SMB1 protocol on both servers. It's enabled.
The server with installed TeamCity Build Agent and TeamCity server(OS Windows 10 ):

The server with SMB share folder (OS Windows Server 2012 ):

In manual mode, all work ok. I successfully copy files from one server to another server into SMB share folder. What is the cause of the problem?

I'm sorry. SMB protocol is disabled on the local network on the router level.
