Troubleshooting Tip: FortiClient showing IPsec VPN profile as 'Unsupported' post upgrade to FortiClient 7.4.4

[mpeddalla]

Description	This article describes the reason for seeing the message 'unsupported' where an IPsec VPN tunnel configuration would be located after upgrading to FortiClient 7.4.4.
Scope	FortiClient 7.4.4 and above
Solution	Instead of the expected IPSEC Tunnel configuration, the following warning is noticed when the FortiClient endpoint is updated to FortiClient 7.4.4 or above from any FortiClient version below 7.4.4: The cause of the message 'Unsupported' is the deprecation of IKE version 1 in FortiClient 7.4.4 and above. Previously existing IPsec tunnel profile configurations utilizing IKEv1 will now show as 'Unsupported' as a result. To rectify the issue , either downgrade the FortiClient to an earlier version or adjust the IPsec configuration to use IKE version 2 in the FortiGate. Refer to below article for configuration examples:  Technical Tip: How to configure IKE version 1 or 2 in IPsec VPN FortiGate  Refer to the release notes for more details:  Special notices | FortiClient 7.4.4 | Fortinet Document Library
