I try to write my own xmpp client on WP using PhoneXMPPLibrary.
Unfortunately, when I create connection like documentation, i have XMPPstate = unknown:(

In debug console I have:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.Net.dll
A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.Net.dll
A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.Net.dll
A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.Net.dll
Any solutions?

This problem is always when in normal client I must add certificate, for any reasons. On other servers it works.
