Hello,
I recently was testing the upgrade of TLS1.2 to TLS1.3 VPN SSL settings on a 40F. I enabled TLS 1.3 support using the following CLI commands:
config vpn ssl setting
set ssl-max-proto-ver tls1-3
set ssl-min-proto-ver tls1-3
end
Now, I am unable to VPN using the FortiClient v7.0.9.0493. It should be noted that I am using Azure MFA for 2-factor authentication.
I am guessing it is a incompatibility between the VPN client and the new TLS version. TLS 1.3?? Are there any prerequisites, i.e. certificates, etc. that should be done before enforcing TLS1.3? Any thoughts and suggestions are welcomed.

Hello Dav
Any error message?
This is the basic error I get when trying:
Hello,
Kindly check and edit the computer registry to enable TLS 1.3:
Go to \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
If 'TLS 1.3' is not displaying as a child path under 'Protocols', create it. 'Right-click' 'Protocols', create 'new key', and name it 'TLS 1.3' as mentioned in following document : https://community.fortinet.com/t5/FortiClient/Troubleshooting-Tip-Windows-10-11-unable-to-connect-to...
I'll have to try that on my personal PC as my enterprise PC locks out editing the registry.
