*Hi,* ** *I want to use OpenSer with TLS but when I try to connect to openser with Windows Messenger I receive this message:*
---------------------------------------------------------------------------------- "Impossible to establish an HTTPS or TCP connection." ----------------------------------------------------------------------------------
*I used the TLS tutorial from openser site to configure TLS; I created the certificates and this is my openser.cfg file:* **
*# $Id: openser.cfg,v 1.5 2005/10/28 19:45:33 bogdan_iancu Exp $*

*tls_ca_list = "/usr/local/etc/openser/tls/calist.pem"*
**
etc......
*I captured with Ethereal the packets exchanged between the server( 192.168.1.5) and the client(192.168.1.98) and on the openserver interface I found this dialog:*

Why are there the TCP RSTs? What is the Encrypted Alert? Is the configuration file exact or not? What can I do to find the problem and solve it?* ** *Thanks!* *Silvia*
