Ac56u/Merlin 376.44 & 376.48, vpn server not working

[soulbadguy]

Hi,
I am having troubling connecting to the vpn server on my AC56U. I tried booth 376.44. and 376.48 and also tried a reset (from the webui) and still nothing.
I tried from booth a linux and windows host , using openvpn.
Form linux :

 openvpn --config client1.ovpn

After a bit of googling , it seems that this is caused by the vpnserver not having root privilege on the router.I don't really know what to do next
Any help would be appreciated
Thanks

This error is client-side. The server on the router definitely runs with all the necessary permissions.

Indeed it was, using sudo solved my issue.
