Ruby on rails app working on http but not on https - nginx

Question

I have a RoR app running in Nginx. I deploy the application to server using capistrano and puma. It works well under this nginx configuration:
upstream puma {
server unix:///home/kiui/apps/kiui/shared/tmp/sockets/kiui-puma.sock;
}
server {
listen 80;
keepalive_timeout 70;
server_name kiuiapp.com;
root /home/kiui/apps/kiui/current/public;
access_log /home/kiui/apps/kiui/current/log/nginx.access.log;
error_log /home/kiui/apps/kiui/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma;
location #puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
}
But I need run the rails app with https to use a Facebook app in it. I created a auto signed ssl certificate following this tutorial create autosigned ssl certificate and changed the nginx configuration to that:
upstream puma {
server unix:///home/kiui/apps/kiui/shared/tmp/sockets/kiui-puma.sock;
}
server {
listen 443 ssl;
keepalive_timeout 70;
server_name kiuiapp.com;
ssl on;
ssl_certificate /etc/ssl/kiui.crt;
ssl_certificate_key /etc/ssl/kiui.key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers AES128-SHA:AES256-SHA:RC4-SHA:DES-CBC3-SHA:RC4-MD5;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
root /home/kiui/apps/kiui/current/public;
access_log /home/kiui/apps/kiui/current/log/nginx.access.log;
error_log /home/kiui/apps/kiui/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma;
location #puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
}
It not work! The browser give me ERR_CONNECTION_TIMED_OUTerror. Someone could help me?

SOLUTION:
upstream puma {
server unix:///home/kiui/apps/kiui/shared/tmp/sockets/kiui-puma.sock;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl;
keepalive_timeout 70;
server_name kiuiapp.com;
ssl on;
ssl_certificate /root/kiuiapp.com.chain.cer;
ssl_certificate_key /root/kiuiapp.com.key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers AES128-SHA:AES256-SHA:RC4-SHA:DES-CBC3-SHA:RC4-MD5;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
root /home/kiui/apps/kiui/current/public;
access_log /home/kiui/apps/kiui/current/log/nginx.access.log;
error_log /home/kiui/apps/kiui/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma;
location #puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
}
I think the problem was the ssl certificate chain. It was not well created.
