Handsake fail on nginx 1.11.13 with OpenSSL_1_1_0-pre6-2220-gb3c42fc25

[Night1]

Hey,

Litte bug report , that took some time to trace down to ct,

I'm running a test server with TLSv1.3 and with the latest few post draft 19 off TLSv1.3 implementation of TLSv1.3 I get server handshake fail in all browsers tested,

However after I comment out ssl_ct in config, site works again

• ssl_ct on;
• ssl_ct_static_scts /etc/nginx/ssl/sct;

nginx build options

nginx version: nginx/1.11.13
built by gcc 6.3.0 20170406 (Ubuntu 6.3.0-12ubuntu2)
built with OpenSSL 1.1.1-dev xx XXX xxxx
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-pcre=../pcre-8.40 --with-zlib=../zlib-1.2.11 --with-http_ssl_module --with-openssl=../openssl --with-openssl-opt=enable-tls1_3 --with-http_gzip_static_module --with-http_addition_module --with-http_geoip_module --with-http_dav_module --with-http_stub_status_module --with-http_sub_module --with-http_ssl_module --with-stream --with-stream_ssl_module --with-mail=dynamic --with-http_v2_module --add-dynamic-module=/opt/nginx-ct --with-mail=dynamic

Is there away to get this working again with newest git of OpenSSL? or should one wait untill TLSv1.3 is final? (looks like draft 20 is coming out very soon)

FYI I'm seeing this too with nginx 1.13.0 and openssl HEAD from today.

I've been seeing this issue for a while atleast 2-3 weeks, at first I thought it was related this this(1). In fact it might still be.
fyi, I also upgraded nginx to 1.13.0 now with OpenSSL_1_1_0-pre6-2248-g7531b3a6c issue precisest

It's a bug in OpenSSL, I've submitted a PR: openssl/openssl#3310
