VPN keeps disconnecting



  • Hi all,

    pfSense 2.3.4-RELEASE-p1 (amd64) running on a Mini PC.

    I have configured pfSense OpenVPN to connect to my VPN Provider and it connects and works fine.  Have also installed the Service Watchdog and set it to monitor OpenVPN.  However, the VPN connection disconnects a couple of times each day and I just restart the service and it connects again.  When it is not connected the Dashboard states it's Offline.

    It happened again this morning and here are the logs:-

    Any ideas on what I can do to stop these disconnections would be appreciated.

    TIA
