Hello, I have a huge problem. We have a FortiGate firewall and connect remotely to our network with the Forticlient VPN. Fortigate support indicates that when attempting to connect the certificate is not accessed. The client receives an error "Unable to establish the VPN connection. The VPN server may be unreachable. (-5)". I realized that there were updates previous day and uninstalled KB5003637 and KB5003254. The VPN will work when these are not installed. I did the same on 6 other systems to prove my theory. Fortigate states that their setup is not the cause and now left me hanging. Does anyone have any advice or has come across this? How do I make Microsoft aware? Thank you
