in my Centos-7 box, /etc/samba/smb.conf contains:
server min protocol = SMB3_11
client max protocol = SMB3_11
client min protocol = SMB3_11
Some non-current windows versions don't support that version, you
may need to try different values til you find one that works.
Whatever you do, you don't want to use version 1.
I'm forcing version 3.1.1 only because all the devices I have
that support SMB also support 3.1.1, so if someone comes along with,
e.g., an old laptop with XP, it won't be able to insecurely talk
to my lan/wan. (and that's a feature, not a bug! ;=) )
