Likely a bug in yahns or the OpenSSL configuration of it.
I have also been running some experimental ruby-trunk or
yahns patches related to https://bugs.ruby-lang.org/issues/12126
so maybe I left something out in a deployment[1]...
Which client(s) are you using?
curl, w3m, lynx on both Debian jessie and wheezy all seem fine.
openssl s_client -connect unicorn.bogomips.org:443 -CApath /etc/ssl/
Also seems fine. As does the following Ruby snippet:
require 'uri'
require 'net/https'
uri = URI('https://unicorn.bogomips.org/')
req = Net::HTTP::Get.new(uri)
res = Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http|
p http.request(req)
end
I suppose there will be problems with old clients that can't
handle SNI or newer/stronger encryption.

I've not advertised the https site for unicorn yet;
it's just an experiment at this point[2]
Given the flurry of 1.12.x releases regarding TLS issues in
yahns, it's safe to say there are likely bugs how yahns does
TLS:
http://yhbt.net/yahns-public/20160229-yahns-1.12.2-unle@shed/t/
Fwiw, here's the OpenSSL SSLContext config I use with yahns 1.12.2
require 'openssl'
ctx = OpenSSL::SSL::SSLContext.new
ctx.cert = OpenSSL::X509::Certificate.new(IO.read(
'/etc/ssl/certs/dcvr.yhbt.net.crt'))
ctx.extra_chain_cert = [ OpenSSL::X509::Certificate.new(IO.read(
'/etc/ssl/certs/dcvr.yhbt.net.chain.crt')) ]
ctx.key = OpenSSL::PKey::RSA.new(IO.read(
'/etc/ssl/private/dcvr.yhbt.net.key'))
ctx.set_params
I'm really not that knowledgeable when it comes to OpenSSL[3].
Is there a WEBrick or similar pure Ruby config you can mimic
the problem with?
[1] Anyways I'm on yahns 1.12.2, now, my curl check runs
periodically and never reported any TLS-related error
in weeks.
[2] And will remain experimental indefinitely given my
lack-of-trust in both the CA system and the quality
of OpenSSL itself.
[3] I'm afraid my attempt to use/read the openssl C library
code back in the the 2000s traumatized me for good :x

I thought so too, but at least google is using https url for their
search result.

FWIW, I see this with Chrome 49 on OSX 10.11, but *not* Chrome 49 on
Debian 8.

To be clear, you have to have a client certificate on your certificate
manager to be prompted.
Server doesn't specify acceptable client certificate CA names, so any
client certificate is ok.

Thanks for the report, I think I just fixed the problem:
ctx.set_params # reasonable defaults for clients, apparently
However, webrick and drb both set VERIFY_NONE for servers:
ctx.set_params(verify_mode: OpenSSL::SSL::VERIFY_NONE)
I've updated https://unicorn.bogomips.org/ with the above change,
can you confirm it works for you? If so, I'll update the yahns
documentation.

It worked -- my browser now doesn't prompt about a certificate :)

The Ruby default parameters on top of OpenSSL seem designed
for client usage. For server usage, requiring client-side
certificate verification is uncommon for HTTPS sites.
So follow what WEBrick does for HTTPS and use SSL_VERIFY_NONE
in our documentation.
