How did you solve it? I am facing the same problem, I've tried to edit Internet Settings and also the registry to enable TLS 1.0, but got connection failed error.

Thanks.

Hi sfc9982,

Can I know what version of Forticlient are you running ?

Thank you,

Hope.

Sorry for that I'm using Juniper's Pulse Secure Connect for my SRX. I got errors on Windows 11, but works fine on Windows 7/10. I captured the netflow, and found after sent several TLS1.0 Client Hello and receive the certificate from the SSLVPN server, it suddenly stop. Then I found your post, I think both your and my problem are related to "TLS version 1.0 in windows settings".

I've tried all my Juniper's VPN client, from 2012's v5.0 to 2022's v9.0.

Add: Turn off beta UTF-8 in Windows settings may help.
