Can't access NAS from Rpi2

[fzinken]

@MrSpectacular

Old (working) file:
[global]
preferred master = no
local master = no
domain master = no
client lanman auth = yes
lanman auth = yes
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
lock directory = /home/osmc/.smb/
client use spnego = no
client ntlmv2 auth = no
name resolve order = bcast host

New (non-working) file:
[global]
lock directory = /home/osmc/.kodi/.smb/
client max protocol = SMB3
name resolve order = bcast host
include = /home/osmc/.kodi/.smb/user.conf

My recommendation:

1. mv .smb/smb.conf .smb/smb.conf.old
2. nano .kodi/.smb/user.conf
   And add only this lines nothing else

client lanman auth = yes lanman auth = yes client use spnego = no client ntlmv2 auth = no

Than reboot. This change should survive the reboot
