Hi,
I’‘ve developped a little bot using the smack library. I’'ve written it in javascript with the JDK6. Everything works fine, except when starting the script and connecting to the jabber server (which is wildfire 3.1). I randomly gets this error:

I’'ve had this on my development server at the beginning, but I attributed it to an error of mine. However, when I transfer this script to the production server, I get this error 9 out of 10 times.
The client connection security is configured as “Optional - Clients may connect to the server using secured connections.”.
In the error logs of the server I get this:

Both should be able to negociate TLS, and sometimes achieve it, but not always. Any idea why?
thanks.
