Reinstalled Enpass on Macook Air and now does not open.

Hi,

I have just tried to reinstall Enpass on my Macbook and when I open it, it gives an error message 'Unable to check for Updates. Please check your internet connection and try again', even though I definitely have an internet connection. I have read that you need to give access to Enpass on your firewall, however can´t find it. 
I use NordVPN as well (if that makes a difference).

Thanks in advance

Niall.
