Please give us some extra information (if it's there), like:
- Command used to mount the share
- Other lines in /etc/exports
- Changes you did in other files (/etc/default/nfs-common, /etc/idmap.conf)
- Is the portmap daemon running?
- Do you have nfs-common installed on the client and nfs-kernel-server on the 
server?
- What does 'showmount -e' on the server tell you?

I see you use the insecure option? The only use of that option that I know of 
is the NFS kioslave, but that will not work in your case because your share is 
a subdirectory. [1]
