I found the solution:

Quote: The reason is, they changed the default protocol version and whatnot, and actually, who cares. People just want to be able to share things with their Windows boxes easily!

Edit

/etc/samba/smb.conf

Add a line

client max protocol = NT1

Restart smb

sudo systemctl restart smbd.service

Now we can see the windows neighbours and the share printers.
