UPDATE: We are now having another user experiencing this issue as well only difference is they are on Windows 10
We have a user with a Windows 11 box that will not connect to VPN using SBL after a system reboot or cold boot. However, when the user signs into the computer they are able to successfully connect to VPN. This issue started after the client software was updated from AnyConnect 4.10.04071 to Cisco Secure Client 5.1.1.42.
When trying to start a VPN connection via SBL the user is quickly displayed the message "The Cisco Secure Client - AnyConnect VPN has sent the following close message to the gateway: Unable to apply proxy settings that are received from the secure gateway." As stated previously, if the user signs into windows 11 normally then connects to the VPN there is no issue and if the user signs off and then initiates a VPN connection using SBL the user is able to successfully login to the VPN with SBL; but if the user reboots the machine they receive the "unable to apply proxy settings" message.
We have tried to do an uninstall and reinstall of the Secure Client suite, which does allow the user to connect using SBL once, then subsequent cold boots or computer restarts will go back to not establishing a connection due to the "unable to apply proxy settings".
Has anyone else been experiencing this issue with a Windows 11 machine with the AnyConnect VPN version 5.1.1.42?
