[Solved] RT-AC68U how to reset OpenVPN server

Hi,
there is a way to completely reset the OpenVpn server in RT-AC68U?
If I shut down the openVPN server the content of the folder

/tmp/etc/openvpn/

is deleted but when i switch on the openVPN server the folder

/tmp/etc/openvpn/vpnserver1

has new certificates/config fils but from GUI settings are the same before shutting down.

And I got this error in general section of OpenVPN:

Certification Authentication / Server certification / Server Key field error!
Please...
