My problem was we were parsing url and generating http options for http request     I was using request url host which already had port number with domain name so had to use request url hostname   var request url   new URL  http   example org 4444 path    var http options        http options  hostname     request url hostname   We were using request url host which includes port number http options  port     request url port  http options  path     request url pathname  http options  method      POST   http options  timeout     3000  http options  rejectUnauthorized     false

Note that this issue can also occur if the domain you are referencing goes down  EG  no longer exists

Another common source of error for  Error  getaddrinfo ENOTFOUND     at errnoException  dns js 37 11      at Object onanswer  as oncomplete   dns js 124 16    is writing the protocol  https  https       when setting the host property in options       DON T WRITE THE  http       var options          host   http   yoururl com       path    path to resource

If you need to use https  then use the https library  https   require  https        options var options         host   eternagame wikia com       path    wiki EteRNA Dictionary        get https get options  callback

In Node js HTTP module s documentation  http   nodejs org api http html http http request options callback  You can either call http get  http   eternagame wikia com wiki EteRNA Dictionary   callback   the URL is then parsed with url parse    or call http get options  callback   where options is      host   eternagame wikia com     port  8080    path    wiki EteRNA Dictionary      Update  As stated in the comment by  EnchanterIO  the port field is also a separate option  and the protocol http    shouldn t be included in the host field  Other answers also recommends the use of https module if SSL is required

I got this error when going from development environment to production environment  I was obsessed with putting https    on all links  This is not necessary  so it may be a solution for some

in my case error was because of using incorrect host value was   var options         host   graph facebook com v2 12        path  path      should be   var options         host   graph facebook com       path  path      so anything after  com or  net etc should be moved to path parameter value

Try using the server IP address rather than the hostname  This worked for me  Hope it will work for you too

I got this issue resolved by removing non-desirable characters from the password for the connection  For example  I had these characters   lt     and it caused the problem  most probably hash tag was the root cause of the problem

If still you are facing checkout for proxy setting  for me it was the proxy setting which were missing and was not able to make the request as direct http https are blocked  So i configured the proxy from my organization while making the request   npm install https-proxy-agent  or  npm install http-proxy-agent  const httpsProxyAgent   require  https-proxy-agent    const agent   new httpsProxyAgent  http   yourorganzation proxy url 8080    const options       hostname   encrypted google com     port  443    path         method   GET     agent  agent

I think http makes request on port 80  even though I mentioned the complete host url in options object  When I run the server application which has the API  on port 80  which I was running previously on port 3000  it worked  Note that to run an application on port 80 you will need root privilege   Error with the request  getaddrinfo EAI AGAIN localhost 3000 80   Here is a complete code snippet  var http require  http     var options       protocol  http        host   localhost     port 3000    path    iso country Japan     method  GET      var callback   function response      var str            another chunk of data has been recieved  so append it to  str    response on  data   function  chunk        str    chunk             the whole response has been recieved  so we just print it out here   response on  end   function          console log str            var request http request options  callback    request on  error   function err               handle errors with the request itself         console error  Error with the request    err message                request end
