The VPN connection terminates unexpectedly! (Error Code: -121)

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

Has anyone tried FortiClient on the new version of MacOS Monterey and been successful?

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.

Thank you AlmightyBob.

Hopefully we will hear from someone at Fortinet that they are aware of this issue and if there are workarounds.

I'm going to give it another week, while I'm on vacation, before I roll back my MacOS. There are plenty of things that could be broken, but the FortiClient is one that I can't do without!

I was wondering if there was a way to install FortiClient without the Online Installer.dmg that detects current version. Mine also says no new client available.

Does anyone have a link to any page listing all client versions for macOS or know where I can download the most current version as an Offline Installer as suggested in this post?

I found the solution to download offline installer in this message, as I wrote before:

https://forum.fortinet.com/FindPost/193145

Just checked the XML that appears and copied/pasted the right string at the end of address

Hope this helps

Mha non so se ti potrà essere utile però io ho risolto installando FortiClinet Vpn aggiornato alla versione per MacOs 7.0.0.0022..una volta scaricata ho spostato come di consueto l'app nella cartella applicazioni.

Inoltre una volta scaricata l'app nella cartella Applicazioni ho aperto il pacchetto contenente l'app con l'applicazione Installer.app...confermato dove chiedeva conferma fino all'avvenuta installazione.

Poi l'applicazione ha funzionato e ha mantenuto la connessione senza problemi.

p.s. ho un Mac mini del 2018 con chip intel.

Just installed Monterey, Forti client stopped working.

Just re-installed it from https://www.fortinet.com/support/product-downloads#vpn (7.0.0.22), works with no issues.

Bump.

The downloadable Forticlient VPN 7.0.2 is not working on the latest Mac OS Monterey.

Is this a known issue? Should our customers migrate to Palo Alto?

7.0.1.0060 works for me after I uninstalled and installed it again.

Hi Tpoxa, are you talking about the Forticlient VPN (only) or the full version?

Now seems the full version is working but not the free VPN version.

Thx

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.
