Server Fault Asked on December 21, 2021
I am getting a 502 error from my nginx server.
I used certbot to configure the ssl and am trying to get http2 enabled and somehow i broke the server.
when I run sudo nginx -t it reads:
nginx: [warn] conflicting server name "website.com" on 0.0.0.0:443, ignored nginx: [warn] conflicting server name "website.com" on 0.0.0.0:80, ignored nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
Here is my sites-available/servername
server {
root /var/www/website.com/html;
index index.html index.htm index.nginx-debian.html;
server_name website.com www.website.com;
location / {
try_files $uri $uri/ =404;
}

} # managed by Certbot
listen 80;
listen [::]:80;

}
when i type netstat -antp
