Error configuring nginx to point to the Jenkins server

I have got Jenkins running on a CentOS 7 VM with IP say 129.215.193.34. So, I can access Jenkins using 129.215.193.34:8080. I wanted to uses nginx so users don't have to type :8080 and just the IP number. After installing nginx and inserting the following in /etc/nginx/nginx.conf

location / {
    proxy_pass http://127.0.0.1:8080;
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

But I am getting a generic error when accessing to 129.215.193.34. How can I know what is wrong here? I can see Jenkins web interface on 129.215.193.34:8080 but nothing on just 129.215.193.34

The rest of the nginx.conf looks like this

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
        location / {
           sendfile off;
           proxy_pass         http://127.0.0.1:8080;
           proxy_redirect     default;

           proxy_redirect off;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
        }

    error_page 404 /404.html;
        location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }
}

You can verify if the nginx configuration is correct by running (as root)

nginx -t

If that is correct, check that the proxy works (you should find something in nginx configuration). Run 

tail -f /var/log/nginx/error.log

and curl to the machine 

curl -I http://<ip>:80/

On SELinux, allow daemons to connect to the service

setsebool -P httpd_can_network_connect on

on the host.
