To make the context clear, I can see (from luci_admin usage) you are
talking about luci used in RHEL 5 (Plone-based).

What is not clear to me is the exact reproducer.
I haven't encountered anything like this so far.

Do you actually accept the certificate[*] for luci?  And this is then
followed by "Connection reset"?  Is it this message browser-specific,
or displayed as a plain page (i.e., you can find this message in
the source of the page)?

And does /var/lib/luci/log/event.log contain anything suspicious
such as tracebacks?  Only messages after "Zope Ready to handle requests"
(and "Plone Deprecation Warning") are important here.

Also, could you be more specific about the web browsers?

[*] It is unrecognized as opposed to common public websites;  simply
because there is no recognized certification authority behind
the certificate.

Please, see that log file and provide browsers details to track
down the issue.
You can also try (change IP address/hostname appropriately):

$ LUCIHOST=192.168.122.243
$ wget --no-check-certificate -q -S --spider "https://${LUCIHOST}:8084/luci/doc";

The result should look something like ("200 OK" status code is important):

  HTTP/1.0 200 OK
  Server: Zope/(Zope 2.9.8-final, python 2.4.3, linux2) ZServer/1.1 Plone/2.5.5

Firewall is OK provided that TCP destination port 8084
(default for luci) is enabled on the machine running luci.

SELinux should be OK as well, or do you see any related
messages in permissive mode/any failure if enforcing?

I hope this will help you,
