Nginx configuration for jenkins on ec2 - amazon-web-services

Question

Im learning nginx and jenkins by setting up a build server on ec2. Setting up jenkins was easy and I was able to even create a test job. I now want to move on to nginx config and mighty confused as to how to set it up. I have hosted zone with my domain, lets call it domain.com . I created an A record for jenkins.domain.com and in the value box put it the IP of the ec2 instance.
Then added this to the /etc/nginx/site-enabled/default
server {
listen 80;
server_name jenkins.domain.com;
return 301 https://$host$request_uri;
}
server {
listen 80;
server_name jenkins.domain.com;
location / {
proxy_set_header Host $host:$server_port;
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;
# Fix the "It appears that your reverse proxy set up is broken" error.
proxy_pass http://127.0.0.1:8080;
proxy_read_timeout 90;
proxy_redirect http://127.0.0.1:8080 https://jenkins.domain.com;
# Required for new HTTP-based CLI
proxy_http_version 1.1;
proxy_request_buffering off;
# workaround for https://issues.jenkins-ci.org/browse/JENKINS-45651
add_header 'X-SSH-Endpoint' 'jenkins.domain.com:50022' always;
}
}
However when I go to jenkins.domain.com:80 I get the site cannot be reached page...

proxy_redirect is not needed here. You can use below site configuration. You should create file jenkins in /etc/nginx/site-available(for ubuntu) or /etc/nginx/conf.d/ (centos or rhel) & copy the configuration in that file. You have to create the soft link on Ubuntu in site-enabled.
ln -s /etc/nginx/site-available/jenkins /etc/nginx/site-enabled/jenkins
Jenkins conf file
server {
listen 80;
server_name jenkins.domain.com;
access_log /var/log/nginx-access.log;
error_log /var/log/nginx-error.log;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_read_timeout 150s;
proxy_next_upstream error;
proxy_pass http://127.0.0.1:8080;
# Add HTTP Strict Transport Security for good measure.
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains;";
}
}
