I am doing that because that's what the log file recommends:
dissect_ssl can't find private key for this server! Try it again with
universal port 0
dissect_ssl can't find private key for this server (universal port)!
Try it again with universal address 0.0.0.0

It's probably not the problem, but at least it rules out the possibility
that the problem is about matching the private key with the right server IP.

I did that as well, but it does not improve my situation.

cheers,

Philippe
