Failed to get tunnel provider's return code

Question

Hi all,

I am unable to connect VPN via FortiClient VPN v7.0.2.0069 on macOS 10.15. I found some solutions at Forums. But it still not work.

- Allowed FortiTray in Security & Privacy - General

- Granted Full Disk Access to FortiClient in Security & Privacy - Privacy

- Used IP address as host instead host name

Please help to provide some suggestion. Many thanks.

I have the exact same issue, when you do get it to function.. finally..it will last a week until one of the two sides release an update and ruins it all over again.  I have come to the understanding that while there is a button on fortinet product downloads for macOS, they clearly could not care less if it works or not.
