The server is a self-built machine with an ASRock J4205-ITX mainboard, 
8GB RAM, a Samsung 470 SSD as system disk and 2x WD Reds as data disks. 
It's running the Debian backport kernel 4.13 (4.14 since yesterday).

The result of 'mount | grep /mnt/temp' on the client is

rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.192.20,local_lock=none,addr=192.168.192.10

where I just set 'soft,proto=tcp', the others were set as default.
