Lost XMPP Messages between GTalk and ejabberd

[Archekal.Imum]

Hi,

we are experiencing strange behavior when trying to communicate with
google talk accounts over our ejabberd based s2s proxy. When sending
authorization requests or normal messages to google talk accounts,
they arrive there successfully. The problem is that possible xmpp
messages returned by google talk never make it to our internal server.
They reach our s2s proxy though. This seems to be an issue between
google talk and ejabberd because this problem only arises when
communicating with google talk.

Any help on this issue would be appreciated.

With best regards,

Michael Grüner
