Hello and happy holidays! we are sorry to inform that we have an Anyconnect server that worked perfectly with openconnect 4.07, but no longer works with openconnect 5.01. We discovered it after upgrade to Ubuntu 13.10. Downgrading openconnect back to 4.07 solves the issue. By not working I mean it cannot estabilish the conneciton, but it doesn't give any meaningful error messages except for "connection failed" after the password has been entered. Which debugging info can I provide in order to trace this problem? Anton
