Not able to access localhost via local IP I want to connect to my local Web Server (NodeJS server) which runs on my MacBook with my iPhone.

On my Mac I can access the server via http://localhost:3000/.
Now all it should take is to replace localhost with my Mac's local IP address like this http://192.168.0.13:3000/. However, on my iPhone I cannot access the server this way and even when I try to open http://192.168.0.13:3000/ on my Mac there is no connection being established.

This is definitely a problem with my Mac and not with my program because when I run the server on Windows and try to connect to it with the local IP address it works just fine.

Also trying this in another Wi-Fi Network does not help or changing the port does not change anything either.

I am using Mac OSX 10.11.5 and my firewall is turned off.

How can I solve this problem?

As far as I can tell the behavior is correct. A basic node web server uses dns.js to resolve any hostname – which itself uses the system's DNS resolution method.

A hostname "127.0.0.1" as well as "localhost" can't be resolved by OS X's mDNS responder (neither non-reverse nor reverse).

So either use your Mac's IP (i.e. 192.168.0.13) or its hostname (e.g. tims-macbook-pro) as hostname. To advertise the service in Bonjour you have to use dns-sd.

Or create several listening IPs like in this q&amp;a.
