Nextcloud Android mobile app - 'Unknown error occurred'

EDIT - just upgraded to v10.0

Nextcloud v9.0.53
CENTOS 7
nginx 1.11.x

I just got a new install of Nextcloud installed (first time using it). I write to storage that is shared via NFS from ‘NAPP-IT’ and I have permissions setup through my ‘fstab’ file.

//172.25.47.111/nappnas/pub/backup/nextcloud /mnt/NEXTCLOUD cifs username=nginx,password=mypass,uid=989,iocharset=utf8,rw 0 0

I can successfully access nextcloud from my desktop on firefox or chrome and upload files, create folders, delete files/folder.

The problem is on my android phone, while I am on my LAN. From Chrome its giving me the error 'Data directory (/mnt/NEXTCLOUD/) is readable by other users. Please change the permissions to 0770 so that the directory cannot be listed by other users.

The next problem is with the mobile app. When I type in ‘http://myipaddress:86’ it reports back with ‘Unknown error occurred’.

Can anyone help me out?

thanks

Got it working - need to change perms on the ‘fstab’ file for mounting.
