Certificates not working optimally with NGINX

Question

I have a test NGINX server that behaves strange with certificates. I have compiled NGINX 1.9.1 and custom openssl-1.0.2a on an Ubuntu 14.04-server.

$ nginx -V
nginx version: nginx/1.9.1
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1)
built with OpenSSL 1.0.2a 19 Mar 2015
TLS SNI support enabled

NGINX compilation:

sudo ./configure --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --lock-path=/var/lock/nginx.lock --with-http_ssl_module --with-openssl=/usr/src/openssl-1.0.2a --with-http_realip_module --with-http_stub_status_module --without-http_browser_module --without-http_geo_module --without-http_limit_req_module --without-http_limit_conn_module --without-http_memcached_module --without-http_referer_module --without-http_scgi_module --without-http_split_clients_module --without-http_ssi_module --without-http_userid_module --without-http_uwsgi_module

OpenSSL compilation

sudo ./config --prefix=/usr

I have set up the server and copied the config files from the production server. I am testing with two sites, one subdomain and one domain. This is the SSL-details for both sites

ssl_ciphers 'AES128+EECDH:AES128+EDH:!aNULL';
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1.2 TLSv1.1 TLSv1;
ssl_session_cache shared:SSL:1m;
ssl_verify_depth 3;
ssl_dhparam /etc/ssl/certs/dhparams.pem;

My main question is why does not Tls 1.2 work on any of the sites. I get the following test on SSL Labs:

TLS 1.2 No
TLS 1.1 No
TLS 1.0 Yes
SSL 3   No
SSL 2   No

I have checked that the server have the TLS 1.2 ciphers.

Production uses and older NGINX and Openssl 1.0.1 and it works there. I have also a test server with NGINX 1.7.1 and OpenSSL 1.0.1f with the same problems with TLS 1.2.

So what am I doing wrong? I have researched it for a while, but not gotten it to work.

AES128+EECDH:AES128+EDH neither of these are in you tls1.2 cipher lists. — Drifter104, Jun 04 '15 at 13:06
Sorry. Late answer as I forgot this over the summer. I forgot to add that I have tried different ssl ciphers, but with same result. I tried the list I got from Mozilla's security generator: https://mozilla.github.io/server-side-tls/ssl-config-generator/. There are ciphers from the list on the server in that one. — Kjetil G, Sep 09 '15 at 04:42
