If you use Apple’s iChat client and have been unable to connect to the jabber.org IM service in the last week, you might need to change your account preferences. The change you need to make is unchecking the “Use SSL” option, as shown in the following image.
For security reasons, you will definitely want to check the “Warn before password is sent insecurely” option. This ensures that your password is never sent over an unencrypted connection (iChat supports encrypted connections over the standard port 5222 using a feature called STARTTLS, so your communications will be encrypted even if you uncheck the “Use SSL” option).
