All transport on IM Gateway cant connect?

Hi, I successfully installed openfire server for linux and my users are happy to use along with their yahoo accounts using the Gateway default settings. But recently, I received a broadcast from openfire server something like “updates on IM Gateway…”. From that moment on, yahoo and other transports cant connect, i tried changing back and fourth what i found on ethereal results, but still no luck. Is there a new update on the ports or even the domain names used by either of these transports?

Thanks in advance on helping.
