Fail to login FortiClient VPN on iOS 15 device

[roy123456]

My Apple device running iOS 15.6.1 is failing to connect to FortiClient VPN

IOS 15.6.1 (FortiClient  7.4.2.0151) – Not work * No popup for enter the username and password

IOS 18.1 (FortiClient  7.4.2.0151) - OK

Does anyone know if there is any compatibility issue between FortiClient 7.4.2.0151 and devices running iOS 15.6.1?
