Ubuntu + Nginx 127.0.0.1 works but localhost doesn't

this one is weird, because I don't have any error messages.

I have a very basic default file:

server {
    #listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6

    root /var/www;
    index index.html index.htm index.php;

    # Make site accessible from http://localhost/
    server_name localhost;

    access_log      /var/log/nginx/default.access_log;
    error_log       /var/log/nginx/default.error_log warn;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to index.html
            try_files $uri $uri/ /index.html;
    }

    location /doc {
            root /usr/share;
            autoindex on;
            allow 127.0.0.1;
            deny all;
    }

    location /images {
            root /usr/share;
            autoindex off;
    }

Now, in shell,

ping localhost 

is fine.

However, in any browser, it displays an error. Chrome, for instance says: "Oops! Google Chrome could not find localhost".

127.0.0.1 on the other hand works in browsers.

Maybe you know where should I check for errors? Nothing in /var/log and other files are clean....

Solution 1:

Firstly, ping is completely relevant to NGINX, you can ping any server that will respond to ping requests regardless of the services running.

Check;

curl -I -v http://127.0.0.1/ - Will see if the site is accessible by local address

curl -I -v http://localhost/ - Will see if the site is accessible by local hostname

curl -I -v http://serverhostname/ - Will see if the site is accessible by servers hostname

nslookup localhost - Make sure 'localhost' is resolving to 127.0.0.1

Post the output of that and if you're still having issues we can give you more guidance
