Hello, during the last three months i've experienced an intermittent problem to federate with google.com. Actually this is a common problem if you browse the web in search for this issue -there are several old threads reporting the same, until some magic happens on Google side and everything goes back to the expected behaviour-. But this time, the strange thing is that some of the virtual hosts i manage on my ejabberd 2.1 server can federate fine, while others don't. Moreover, these domains with problems later can do s2s fine with Google, without any change on my side. The symptom is always the same: during s2s handshake the outgoing connection from my server closes by timeout waiting for a reply from Google on the wait_for_validation state. But i don't see why some domains remain unaffected while others don't. If anybody is experiencing the same issue i would be glad to know about it.
Regards, Juan Pablo
