Access Network SMB Share on a NAS

[deltapy]

Hi there,
total NOOB here.Trying to learn some Pyhton starting from "basic" automation tasks.
What I'd like to do is telling a podcast app to update and d\l new episodes and move them to a NAS share folder. The first step is complete. What I'm having a hard time with is accessing my WD MyCloud server. I'm using Python3 on a raspberry PI 4. I've tried the following code with success to access two other shares. One is an Ubuntu machine and the other a debian antix based machine.
I can't access the NAS no way. This is the code

from smb.SMBConnection import SMBConnection

host: str = "192.160.0.8"  # ip or domain name
username = ""
password = ""
conn: SMBConnection=SMBConnection(username,password,"","",use_ntlm_v2 = False)
result = conn.connect(host, 445)


localFile=open("/home/delta/Storage/file","rb")
conn.storeFile("System4", "testfile", localFile)
localFile.close()

IF i try that code to access the NAS server I've been given the

smb.smb_structs.ProtocolError: Server does not support any of the pysmb dialects. Please email pysmb to add in support for your OS

error.
After long googleing I see the pysmb only supports SMB1\2 while my WD NAS Server should run the SMB3 version. I don't know whether that's the issue, nonetheless I've tried to use smbprotocol or smbclient, but, after installing the modules, I get a <no module named smbclient or smbprotocol> when running the script.

Hope to find some help here guys..
