Operation not Permitted on TUN Device?

Web VPS

So I've had this server for a week or two. I connect all my servers to a private virtual network for security. But 3 days ago my OpenVPN tunnel went down to my network. I went to debug and found this:

TUN was working, but then just stopped. This is the error given:

# openvpn --mktun --dev tun0 Fri Jan 10 19:58:53 2014 Note: Cannot open TUN/TAP dev /dev/net/tun: Operation not permitted (errno=1) Fri Jan 10 19:58:53 2014 Cannot ioctl TUNSETPERSIST(1) tun0: Bad file descriptor (errno=9) Fri Jan 10 19:58:53 2014 Exiting

TUN is enabled:

# ls -l /dev/net/tun crw-rw-rwT 1 root root 10, 200 Jan 10 16:45 /dev/net/tun

# cat /dev/net/tun cat: /dev/net/tun: File descriptor in bad state

I contacted my provider to fix the issue. He reported that he followed these steps on my container: http://openvz.org/VPN_via_the_TUN/TAP_device

There was no change and the ticket is now categorized under "Server Related Queue".

Is there solution or fix that any has found? And is there a way to figure out if this is my issue or my provider's? Or any other helpful information.

Thanks for any assistance.
