Forum: NGINX NGINX not binding to localhost:80 only 127.0.0.1:80

Ive had this issue with tomcat apache in the past and always fixed it by 
specifying localhost as part of the listen directive - not working with 
NGINX on OS X.

NGINX is responding to 127.0.0.1 - but localhost it just drops the 
connection (its not refusing the connection, just dropping it)

Is there a way to fix this I have tried listen *:80, listen localhost:80 
and still I cant reach it through the browser using localhost.

localhost is resolvable with ping and has its entry in the hosts file.

Posting your configuration would probably help people diagnose your
issue more easily ...

lsof says NGINX is listening on localhost

nginx     3315           root    8u  IPv4 0xfd9b22b8ee1eac23      0t0 
TCP localhost:http (LISTEN)

When I run another web server on that port localhost works fine but not 
with this NGINX config.

As of now

    listen localhost:80;

will only listen on first ipv4 address resolved from the localhost
name.  If you want nginx to listen on all ip addresses (likely
ipv4 127.0.0.1 and ipv6 ::1 in your case), you have to list them
explicitly, like this:

    listen 127.0.0.1:80;
    listen [::1]:80;

Or listen on both ipv4 and ipv6 wildcard addresses, like this:

    listen *:80;
    listen [::]:80;

Note well that to work with ipv6 addresses you need nginx compiled
with ipv6 support.

Maxim,

I used the

listen localhost:80;
listen [::]:80;

And now the server responds to localhost.

Not sure why this would be happening unless nginx was binding to v6 
rather than v4
either way its nice to have that annoyance gone.

Thanks!

The problem is not that nginx binded to ipv6 - it instead binded
to ipv4 only.  But the tool you've used to connect to nginx only
used ipv6 (or used ipv6 as first option, and didn't fallback to
other addresses).

I suspected that could the case as well I just didn't think google 
chrome and safari would both exhibit that behavior and the other web 
servers I start on the sane port aren't even ipv6 aware
