OpenVPN - Viscosity Mac - Dropping Connection



  • I've had OpenVPN up and running for about a month and I've been able to connect to it using Viscosity on my Macbook. It works great.

    I downloaded Viscosity to a second computer and was also able to connect to my pfsense by VPN.

    I haven't changed anything in the config and now it's dropping the connection roughly every minute. I tried rebooting the pfsense box with no avail. This is the log when it drops:

    Any ideas?

  • What mode is the OpenVPN server set to on pfSense?

    What do the OpenVPN logs show on pfSense?


  • LAYER 8 Netgate

    Dropping connections every minute usually means you are connecting from two different clients and have not configured the server to accept connections from multiple clients with the same credentials.
