My server is running Ubuntu 18.04 with nfs-kernel-server running under systemd, but when I try to connect from Oculus GO (this is standalone VR system running Android) or from Xiaomi Mi6 I get error that there is no access to /home/hoshi/NFS dir (and everything should work fine).
My /etc/exports setup:
I tried also RO options, I assume I don't need to setup certain IP to get access (so no *)? /home/hoshi/NFS belongs to hoshi group and user also there are drwxrwxr-x permissions.
I'm not familiar with NFS and there is small information how to configure it, thanks tho.
