Can't connect to localhost ECONNREFUSED

I Just did a fresh install of version 0.7.2 and I get the following error trying to load the schema when I put my endpoint in.

Error: connect ECONNREFUSED 127.0.0.1:3000
    at Object.exports._errnoException (util.js:1026:11)
    at exports._exceptionWithHostPort (util.js:1049:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1081:14)

The endpoint is: http://localhost:3000/api/graphql Weirdly enough if I use ngrok to forward requests to port 3000 and use the endpoint: https://bf29c0e6.ngrok.io/api/graphql, everything works.

Any clues to what the issue could be ? I tried installing with brew first and then uninstalled and tried the .dmg file from the releases page but I'm still having the same problem

Any luck with this ?

Same here on v 0.7.2:

Error: connect ECONNREFUSED 127.0.0.1:3000
    at Object.exports._errnoException (util.js:1026:11)
    at exports._exceptionWithHostPort (util.js:1049:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1081:14)

Graphql server is running within a Rails app on port 3000 and doesn't report any refused connections.

Also having the same problem. @dzanfardino @ivdma @MikeyParton did any of you guys ever sort this out?

Nope, GraphiQL app went straight into the Trash.

@ivdma :-) frustrating, I'm sure.

As It turns out, I didn't have to throw it in the trash (It has worked well for me in many other projects).

It appears this problem is due to some sort of a security issue (cors or something like that).

Here's how I resolved it (on mac osx) :

1. I added an entry to /etc/hosts:

   127.0.0.1    myproject.example.com
   

2. Then, I configured my testing webserver to listen for connections coming in from host myproject.example.com.

3. Finally, I navigated to myproject.example.com/endpoint using GraphiQL and did not get a connection refused error.

This keeps cors errors from blocking connections. Hope this helps.
