Failed to get tunnel provider's return code

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.. 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.


Hi @downstorffleon ,


Hope someone finds a solution.


Hi @g4ry415 ,

Could you please check, is Mac’s Built-in Firewall enabled?, If it is enable, please try to disable it and check it again.

Hi @msanjaypadma ,


The Firewall is turned off in Security & Privacy - Firewall. So I tried to turn it on and off again. But it still can't connect to VPN. Pressing 'Connect' button will take you back to the login page.
