We experienced the same issue. We had two domains running on the same
ejabberd node. One could communicate with the Google Talk servers, the
other could not. At the time I dug into the problem and my conclusion
was a buggy Google s2s implementation. In our case, one day it
suddenly started to work. No configuration changes or restarts. I have
yet to hear any comments about this issue from the Google Talks team.
