How to make VPN stay on?

Im on 17.1 I have a VPN connected, but every time computer goes to sleep or reboots it disconnects. very very annoying and sometimes I miss it and am functioning without a VPN. How do I make it so that it persistently stays on?

Why doesn't Zorin do this by default? They do miss some very basic features that are standard on many other OS.

Could You tell us what VPN Service do You use?

I would rather not. It is quite an obscure one... but it is simply the Zorin setting that is disconnecting not the VPN. I use this VPN on other devices using the OpenVPN GUI but that is not used on Zorin
