I am using the Cisco AnyConnect client on my Windows 10 PC "anyconnect-win-4.7.03052-predeploy-k9" and it works great connecting to my newly deployed ISR4331. When I install the same software and the same XML profile on my other Windows 10 PC I get the error "The VPN client failed to establish a connection". I'm not sure why it isn't working. I thought I could just install the Anyconnect software and XML profile and run it on any PC using the same username and pw. I installed it on my Chromebook and it works fine. I really need to resolve this. We are cutting over from old Cisco EOL/EOS hardware to new Cisco ISR4431/ISR4321 devices and if I canāt get the Cisco AnyConnect working on each userās Windows PC then we can cut over to the new Cisco gear.
I ran a debug on the ISR4331 and this is what I'm seeing right when I get the message "The VPN client failed to establish a connection" on the Windows PC. What else can I do to debug this problem? I opened up a Cisco support ticket but still waiting for am engineer to help out.
