Hello, I'm trying to replicate a working Cisco AnyConnect install on a windows laptop to a linux/debian machine using openconnect. I'm using just the basic settings to launch openconnect but no matter what combination of username or password or various other options I've tried have I been able to get past the "please enter your username and password" prompt. Turning on verbose mode gave me some output after I first enter my username/password that looks like this: Failed to write to SSL socket: Error in the push function. SSL negotiation with vpn.mysite.com Server certificate verify failed: signer not found Connected to HTTPS on vpn.mysite.com > POST /+webvpn+/index.html HTTP/1.1 After that it goes through some more http responses and asks me for my username/password again. Is there anything wrong here or is there someplace I can look at my working install for more details? I'm really not sure where I should even be looking in an attempt to debug this.
