I've got some help on the samba mailing-list.
These settings on the server smb.conf has no effects:
min protocol = SMB2
max protocol = SMB3

However the following settings on the client smb.conf works:
client min protocol = SMB2
client max protocol = SMB3

Connection through smbclient is done with protocol SMB2_10 (checked
with smbstatus).

Connecting throught Nautilus/Gvfs is also done with protocol SMB2_10,
however it is not possible to copy anything anymore (I got an error
"invalid argument", throught Nautilus or throught command-line cp).

There is no problem if I use the protocol NT1.

server: Debian Stable + samba 4.2.10 + kernel 4.7 (amd64)
client: Debian Stable + smbclient 4.2.10 + kernel 4.7 (amd64) + gvfs
        1.22.2-1
