When I then press F5 to reload the directory, the content loads (pic2). Log:

But when I then open a file, I get pic3. Log:

$ showmount -e 192.168.0.50
Export list for 192.168.0.50:
/mnt/data/libvirt 192.168.0.21
/mnt/data/media   (everyone)

Mounting the nfs share manually (and opening files then) with "mount
192.168.0.50:/mnt/data/media /mnt/" works without problems.
