Frequent Disconnects

I have just tried the PIA client, Viscosity client and OSX inbuilt VPN and I am getting intermittent disconnects. Once disconnected I have to close the Viscosity client an re-load it as it won't reconnect on it's own. Here is an extract from it's log.

    Hey DavidG!

    Thank you for reaching out to us. 

    I have looked over the log that you had sent in and I can see the following error:

    Apr 10 16:30:39: Opening utun (connect(AF_SYS_CONTROL)): Resource busy
    Apr 10 16:30:39: Opening utun (connect(AF_SYS_CONTROL)): Resource busy
    Apr 10 16:30:39: Opening utun (connect(AF_SYS_CONTROL)): Resource busy
    Apr 10 16:30:39: Opened utun device utun3

    What this indicates, is that the utun adapter is not able to work, as there are multiple VPN connections at one time. Or if you have security software(like ESET) it is trying to protect the utun. 

    What I do recommend is that you remove 2 of the VPN setups and try connecting to only one. I do recommend that you try the application over the other two, as it does provide more features. 

    Please let us know how you get along. 

    Thank you,

    This is the real problem

    Apr 10 17:47:56: TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
    Apr 10 17:47:56: TLS Error: TLS handshake failed

    I use the same VPN client Viscosity for work and for other vpn providers and I don't get any disconnects from using them.
