Hi,
I already tried this but after a double check I saw that it was not set correct to 0s. Now it is working and also the connection is possible, around 5 seconds faster.
No idea why this setting is set as default. It hink there will be many problems with this. What a research to find the iroot cause.
Thanks

These numbers are quite high, yes. The web application probably hits a
timeout
before the connection is established.
This attempt was made from the web application's host?
Did you also try a manual handshake test with telnet? Would be
interesting to
know at which stage these long waits occur.
What about Wireshark? Were you able to analyze a network trace?

You probably should disable ident lookups, I don't see why anyone would
need
those today and by doing so you get rid of a few seconds of waiting.
What's rfc1413_query_timeout set to in your configuration? Maybe this
explains
the ~6 seconds connection time.
Apart from that I cannot find any issues in this debug trace.
Bye,
Tom.
