OpenVPN getting disabled


I have openVPN enabled on my AR300M router with the force VPN option on. The provider is PIA.

The problem is, every night the VPN gets disabled for some reason (the enable option in the menu gets unchecked).

When this happens, sometimes the VPN is still connected (I’ve checked through IP address), but sometimes it’s disconnected and the “force VPN” option is not working so the router is broadcasting it’s real IP to the internet, which is very annoying.

This problem doesn’t happen when I do a reboot from the menu.

Any ideas as to why this is happening?

Forgot to mention, I have 2.25 firmware and using NAND.

No idea why this is happening - suggest a new firmware install without saving settings and re-try.
