Failed to connect to server. The reason may be that the encryption methods supported by the server are not enabled in the security preferences.
Please note that some encryption methods are no longer supported, and that access will not be possible until the website has been upgraded to use strong encryption.
Make sure your internet connection is active and check whether other applications that rely on the same connection are working.
Check that the setup of any internet security software is correct and does not interfere with ordinary web browsing.
If you are behind a firewall on a Local Area Network and think this may be causing problems, talk to your systems administrator.

===========
I'm limited to work with a live XP system with an Opera browser (the config above) so after awhile I observed that some sites I was checking it from time to time doesn't open anymore.
Can someone tell me what I have to do, or why is that and what I can use to have backward compatibility with the old XP and I can browse those sites?
Any help is apreciated.
Thanks in advance.
