connect ehostunreach 0.0.31.153:80

Hi, I have a project with restify that sends data to an api with axios. When I start both apis locally the axios shows this message

{ Error: connect EHOSTUNREACH 0.0.31.153:80 - Local (192.168.2.112:64676)
    at Object._errnoException (util.js:1024:11)
    at _exceptionWithHostPort (util.js:1046:20)
    at internalConnect (net.js:971:16)
    at GetAddrInfoReqWrap.emitLookup [as callback] (net.js:1106:7)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:97:10)
  code: 'EHOSTUNREACH',
  errno: 'EHOSTUNREACH',
  syscall: 'connect',
  address: '0.0.31.153',
  port: 80

I noticed that this post #1228 is similar to mine, but it's closed.
How do you solve this?

environment

os: macOS
node: v8.9.3
npm: 5.5.1
axios: 0.18.0

IP addresses can't start with 0. Thus the EHOSTUNREACH error. See here for example: https://superuser.com/questions/665502/why-cant-ip-addresses-start-with-0-or-255

This issue should be closed.

but the local ip does not begin with 0. As it is construction, the project is raised in the local address (localhost or 127.0.0.1)

this message is not making sense because of this

You'd need to find why the address is

address: '0.0.31.153',

Hi @carvalhoviniciusluiz , I encountered this problem today. By doing debug, I found some reason may cause this problem.

It's about your system bash/zsh proxy settings

export https_proxy=localhost:8888
export http_proxy=localhost:8888

axios will automatically detect your default proxys and use them.

axios/lib/adapters/http.js

var proxy = config.proxy;
    if (!proxy) {
      var proxyEnv = protocol.slice(0, -1) + '_proxy';
      var proxyUrl = process.env[proxyEnv] || process.env[proxyEnv.toUpperCase()];
      if (proxyUrl) {
        var parsedProxyUrl = url.parse(proxyUrl);
        proxy = {
          host: parsedProxyUrl.hostname,
          port: parsedProxyUrl.port
        };

        if (parsedProxyUrl.auth) {
          var proxyUrlAuth = parsedProxyUrl.auth.split(':');
          proxy.auth = {
            username: proxyUrlAuth[0],
            password: proxyUrlAuth[1]
          };
        }
      }
    }

the result of url.parse('localhost:8888'):

get the wrong hostname

Then your dns will find this hostname, as a result, it returns 0.0.xx.xxx, which throw errors.

so just remove https_proxy and http_proxy and restart your terminal

so just remove https_proxy and http_proxy and restart your terminal

For the sake of simplicity, you can remove them in the following way:

npm config delete http-proxy
npm config delete https-proxy

so just request http:// 0.0.0.0:1337/your/path
then url will be right

This error is also fired when you write just the IP @ without the protocol.
Even with 127.0.0.1 you should add http://.
Hope that was helpful .

I've just add the http:// before the endpoint url and problem is solved then.
