Jenkins Https reverse proxy configuration is not working in centos - nginx

Question

I have installed nginx and jenkins server in centos. I want to connect my jenkins server with https. so I have configured reverse-proxy. But its not working, I'm getting the following error
Below are the my configuration values
File - /etc/nginx/sites-enabled/default
server {
listen 80;
return 301 https://$host$request_uri;
}
server {
listen 443;
server_name 134.68.44.235;
ssl_certificate /etc/nginx/cert.crt;
ssl_certificate_key /etc/nginx/cert.key;
ssl on;
ssl_session_cache builtin:1000 shared:SSL:10m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
ssl_prefer_server_ciphers on;
access_log /var/log/nginx/jenkins.access.log;
location / {
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 $scheme;
# Fix the “It appears that your reverse proxy set up is broken" error.
proxy_pass http://localhost:8080;
proxy_read_timeout 90;
proxy_redirect http://localhost:8080 https://134.68.44.235;
}
}
File /etc/default/jenkins
JENKINS_ARGS="--webroot=/var/cache/jenkins/war --httpListenAddress=127.0.0.1 --httpPort=$HTTP_PORT -ajp13Port=$AJP_PORT"
Note : I can able to access the jenkins site using http://134.68.44.235:8080
But I can't able access it using https, I installed certificates and followed the steps from this article
I'm not sure what I'm missing, Anyone kindly advise me on this.

This snippet below should work well, you'll have to edit the content sections to match the FQDN or IP you want Jenkins to serve the web UI, together with the valid SSL CERT path and SSL KEY path if you want to provide https.
upstream app_server {
server 127.0.0.1:8080 fail_timeout=3;
}
server {
listen 80;
server_name <FQDN OR IP>;
return 301 https://$server_name$request_uri;
}
server {
listen 443;
server_name <FQDN OR IP>;
ssl on;
ssl_certificate /<PATH>/<TO>/<YOUR SSL CERT>;
ssl_certificate_key /<PATH>/<TO>/<YOUR SSL KEY>;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers RC4:HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
# Redirect any /* request to port 8080
location / {
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 $scheme;
if ($request_method = 'GET') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Headers' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST';
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range,Location';
}
proxy_redirect http:// https://;
proxy_pass http://app_server;
}
}
