Hello! Thank you for all these information. I've connected to VPN using Cisco AnyConnect. I tried with different possible names and server name as VPN, but I got "No service" error. Is there anyway we can list the available VPN connection names?

@tuxian0 If you're using the Cisco AnyConnect client then none of this will work. You could try scripting the Cisco client directly, or see if your VPN configuration can be redone with the native macOS VPN client, configured in System Preferences -> Network.

Either this doesn’t work in 10.15 or it doesn’t work with the NordVPN IKE client. Iot doesn’t show up in the scutil —nc list command

@LwsBtlr , this is likely because you are using IKEv2 services. I had a similar issue trying to fix my VPN to auto reconnect. Below is the solution I eventually used. This may point you in the direction to solve your issue:

I simply downloaded the precompiled app here.

If you are interested in the source code that makes it work, you can find it on GitHub here: https://github.com/Timac/VPNStatus
