The status always remains grayed out or turns into a red light and back to gray within a second after clicking “Open tunnel”.

And the console is empty after you change anything or fail to open tunnel.

Root Cause

If SecuExtender IPsec VPN client cannot work on your macOS, it's likely the default security settings are preventing it from loading. It's because the default setting only allows applications that have been downloaded from APP store.


Go to Privacy & Security > Security, you will see this message "System software from application SecuExtender VPN Client was blocked from loading". Click Allow and re-launch the application SecuExtender VPN Client.

To prevent similar incidents, you may select App Store and identified developers under the header “Allow apps downloaded from", it will request the credentials to make changes.
