been trying on builds since beta 2 including yesterday's (27 July) release w/ no success. unfortunately we have to run vmware and go through a windows or ubuntu vm to get into the office.

the logs just show an extensive amount of this (below, over and over) followed by some IPv6 failed attempts just before it fails to connect.

Running on an intel 2019 macbook pro.

I had a similar problem with "old" version of FC (Sorry I don't remember which one, since I didn't check before uninstall): every time I tried to connect, it said it couldn't, without any error message. I tried to download version 7 from site but I had another problem (it was "forticlientupdate" app and it gave the message "no updates found" - that's why I uninstalled the old one, to try to avoid this behavior). I came here and I found, in another thread, a hint to download offline installer, so I got version 7.0.0.0022 and it worked like a charm.

Hope this could help

Hey All,

I hope this will work for everyone. It worked for me! Here are the steps on how I solve the problem.

[ol]

Turn OFF Private Relay by going to System Preferences>Apple ID>iCloud. And uncheck Private Relay (Turning this option OFF connecting to VPN might still not work)

Go to forticlient website and download the ZTNA Edition which includes SSL VPN with MFA

Run the installation

Restart Forticlient

Connect to VPN

Instead of entering the Token, the FortiToken mobile will show an alert popup to approve the connection. If there is no popup alert, simply enter the token number.

Chic@s les dejo unas versiones de Forti en el siguiente link, quizás les puede servir. A mí me sirvió una de esas versiones en macOS Monterey Versión 12.6.8.
