OpenVPN Client dropping connection

[omegadcuk]

Hi I am using an ASUS AC RT68U router flashed with asus-Merlin 378.55_0.

I have setup LiquidVPN modulating server on port 9201 and it works well for a few hours. then disconnects and never re-connects. Reconnecting just errors, reboot and restart VPN is only thing that works.

I notice two things from the logs:

1. There is an authentication failure but I don't understand why.

Oct  8 06:19:48 openvpn[4355]: SENT CONTROL [titan]: 'PUSH_REQUEST' (status=1)
Oct  8 06:19:48 openvpn[4355]: AUTH: Received control message: AUTH_FAILED
Oct  8 06:19:48 openvpn[4355]: SIGTERM received, sending exit notification to peer

2. The logs suddenly start logging as 1 Jan 0:00:00:00 after VPN disconnects.

Any help greatly appreciated as at the moment my VPN is unusable for more than a few hours and does not restart.
