[Samba] Windows / / Windows 10 randomly lost connection to Samba share

[basti]

I have set

 grep client /etc/samba/smb.conf
    client min protocol = SMB2
    client max protocol = SMB2

stop and start samba but connections are still smb3_11

/etc/init.d/samba stop
[ ok ] Stopping smbd (via systemctl): smbd.service.
[ ok ] Stopping nmbd (via systemctl): nmbd.service.
/etc/init.d/samba start
[ ok ] Starting nmbd (via systemctl): nmbd.service.
[ ok ] Starting smbd (via systemctl): smbd.service.
