I received this packet from client:
<iq id="dgl8K-24" to="admin@localhost/testchat" from="tp@localhost/testchat" type="error">
<query xmlns="http://jabber.org/protocol/bytestreams"
sid="jsi_8684670244487833690"
mode = "tcp">
<streamhost jid="proxy.localhost" host="null" port="8086"/>
</query>
<error code="404" type="CANCEL">
<item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
<text xml:lang="en" xmlns="urn:ietf:params:xml:ns:xmpp-stanzas">Could not establish socket with any provided host</text>
</error>
</iq>
Why is host null?
