In order not to loose this bit of information that came in via 
#debian-perl IRC:


```

15:27 < ntyni> it's a TLSv1.3 thing, hacking in SSL_version => 'TLSv1_2' 
makes it pass
15:27 < ntyni> the underlying error seems to be "SSL wants a read first"
15:29 < ntyni> but I can't really tell if the fault is in 
HTTP::Daemon::SSL, HTTP::Daemon, IO::Socket::SSL or Net::SSLeay and my 
eyes bleed already
15:32 < ntyni> 
https://wiki.openssl.org/index.php/TLS1.3#Non-application_data_records 
is presumably related
15:46 < dam> that test fails differently for me: Bad arg length for 
Socket::inet_ntoa, length is 16, should be 4 at 
/usr/share/perl5/HTTP/Daemon.pm line 51.
15:46 < dam> and the argument is 16 binary zeroes (like ip6 0::0)
15:50 < ntyni> that's weird given t/ssl_settings.req has 127.0.0.1
15:51 < ntyni> HTTP::Daemon is IPv4-only and I'd expect issues like that 
when passing 'localhost' to it
15:58 < dam> hmm. will look more
16:07 < ntyni> so I suppose the issue is with the client not the server; 
I can interact fine with the server side with curl
16:09 < ntyni> the client is Test::WWW::Mechanize, which uses 
LWP::Protocol::https underneath (-> Net::HTTPS -> IO::Socket::SSL)
16:11 < ntyni> and I guess the client blindly writes the HTTP request 
without reading non-application data records out first

[...]

20:30 < ntyni> seems like a client problem indeed; POSTing to 
facebook.com with LWP and TLSv1.3 hangs for me too
20:30 < ntyni> as in perl -MLWP::UserAgent -e 
'LWP::UserAgent->new->post("https://facebook.com", { data => "foo" }) or 
die'
20:31 < ntyni> sticking ssl_opts => { SSL_version => 'TLSv1_2'} in there 
makes it go away
