I am using FortiClient VPN Version 7.4 on Windows 11 24H2. When I connect to the VPN using FortiClient VPN, an IP address is not assigned, and I am unable to access the internet after connecting to the VPN. If I uninstall and then reinstall FortiClient VPN, it connects without any issues the first time, but from the second attempt onward, an IP address is not assigned, and I cannot connect to the internet. This issue occurs on two identical PCs. Of course, when using the VPN, the Wi-Fi is set to DHCP. If anyone knows the cause of this issue or has experienced the same problem, I would appreciate your help.

Hi, thank you for the response. The Windows update mentioned in the URL was not present on the affected PC. However, I was able to resolve the issue myself. The cause was that the FortiClient VPN internet adapter was not set to DHCP. I had a batch file assigning a static IP of '0.0.0.0' to 'Ethernet,' the built-in wired LAN, but since the affected PC did not have a built-in wired LAN, the FortiClient VPN internet adapter was named 'Ethernet,' causing the batch file to set it to a static IP
