Hi guys, Any idea what would cause the ?illegal version? error? I?m assuming it?s referring to the SSL/TLS version. This server (ocserv) works fine for other users of OpenConnect-GUI and also for this particular user if he uses OpenConnect on Android instead of Windows. (Also OpenVPN on the same computer works without issues.) 2014-11-02 17:54 POST https://XXXXX/ 2014-11-02 17:54 Attempting to connect to server 123.123.123.123:443 2014-11-02 17:54 SSL negotiation with XXXXX 2014-11-02 17:54 SSL connection failure: A record packet with illegal version was received. 2014-11-02 17:54 Failed to open HTTPS connection to XXXXXX 2014-11-02 17:54 Authentication error; cannot obtain cookie 2014-11-02 17:54 Disconnected Thanks, Niels
