Timeout when XMMP server sends "iq-auth" twice

Hi,

The XMPP server I use sends sometime the following stanza twice in a row:

2017-07-11 06:30:58,175 IN : <stream:features xmlns:stream="http://etherx.jabber.org/streams"><auth xmlns="http://jabber.org/features/iq-auth"/><mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><mechanism>SCRAM-SHA-1</mechanism><mechanism>PLAIN</mechanism><mechanism>ANONYMOUS</mechanism></mechanisms><ver xmlns="urn:xmpp:features:rosterver"/><starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/><compression xmlns="http://jabber.org/features/compress"><method>zlib</method></compression></stream:features>

When it occurs the resulting sequence is:

2017-07-11 06:30:58,190 OUT: <auth xmlns="urn:ietf:params:xml:ns:xmpp-sasl" mechanism="SCRAM-SHA-1">biwsbj0xMjM0NS0xMjM0NS0xMjM0NS0xMjM0NS0xNSxyPUVieXF3V3dSTXBUQUw0NCtBN29MSUE9PQ==</auth>

2017-07-11 06:31:18,191 IN : <close xmlns='urn:ietf:params:xml:ns:xmpp-framing' />

And rocks.xmpp.core.session.NoResponseException: Timeout while waiting on resource binding feature. is thrown.

Before asking the server to fix the issue (which is a very tedious process...) I would like to be sure that the behavior of Babbler is the right one, and as I'm not proficient enough in XMPP I would appreciate your help...

Thanks,

Jacques

    Hi Jacques,

    Babbler is sending a <close/> and I am not sure why.

    Could you please do something similar to this (before connecting/login): xmppClient.addSessionStatusListener(e -> {
    if (e.getThrowable() != null) { e.getThrowable().printStacktrace(); } } });

    And see, if it prints something?

    Unfortunately, or fortunately, I was wrong regarding how fast the issue will be fixed on server side. Actually I already got a patch and the fix seems, so far, OK. Anyway I'll follow your instructions and I'll let you know if I get something.

    Trying with another XMPP server instance (not fixed yet), I got several "Timeout while waiting on resource binding feature" but nothing coming from the "xmppClient.addSessionStatusListener"

    Does the server send the <bind/> feature? Exceptions during login are special, maybe they don't show up in the listener (although I thought they would). However, you should get the exception from the login method then (throws).
