Unable to Connect to IPsec VPN on macOS Sequoia 15.3.1

[klebson]

Hello,

I’m using macOS Sequoia 15.3.1 with FortiClient VPN 7.4.2.1717, but I’m unable to connect to the IPsec VPN.

I’ve seen other forum posts suggesting enabling FortiTray, FortiClientProxy, and FortiClientPackageFilter under Network Extensions, but these options do not appear for me.

Is there a solution for this issue?

Thank you in advance.

Hello Klebson

On your MacOS try sniff traffic to see if FCT is trying to send any connection request to your remote FGT.

tcpdump host x.x.x.x     (Where x.x.x.x is the public IP of your FGT)

If you have admin access to your FGT then you may try diagnose the connection.

diagnose vpn ike log filter ...     (use the right filter if needed) 
diagnose debug application ike -1
diagnose debug console timestamp enable
diagnose debug enable

Hope it helps
