looking at the error WARNING: do_connect: Connection to 192.168.xx.xx failed (Error NT_STATUS_IO_TIMEOUT) and google it, it seems to be something with SMB versions:

his is most likely because the box your trying to do smbclient uses an outdated (and insecure) version of SMB such as SMBv1.

You'll need to edit the smb.conf in your machine and specify the client min protocol into CORE. You'll also need to specify the client max protocol into SMB3.

More information here: https://www.samba.org/samba/docs/current/man-html/smb.conf.5.html

Steps: On your host machine:

sudo nano /etc/samba/smb.conf
Add the following settings under Global Settings:
client min protocol = CORE
client max protocol = SMB3
Write (Ctrl + O) and Exit (Ctrl + X) nano text editor.
Retry smbclient

see here

as my nas is on SMBv3 i dont want to downgrade it.

Actually it's the other way around. This most likely means that your NAS only supports an outdated SMB version, so this addon refuses to connect. You could take a look at the compatibility_mode option --> https://github.com/thomasmauerer/hassio-addons/blob/master/samba-backup/DOCS.md#option-compatibility_mode

Hi, tried that also, but gives the same error message. The SMB on my NAS (Synology) is set to:

Maximum SMB3 Minimum SMB2 and large MTU

Please let me know if you need more information
