Could not proxy request /pusher/auth from localhost:3000 to http://localhost:5000 (ECONNREFUSED)

Question

I am trying to create a chat app using reactJS and pusher, i am getting this error-

Could not proxy request /pusher/auth from localhost:3000 to http

Answer 1

In your node module include

{
...
  "proxy": "http://127.0.0.1:5000"
}

Where the ... simply means you should append the proxy ip to it.

Also, if you are using axios, doing axios.post('api/users') works and not axios.post('/api/users')

Answer 2

If you can't connect to localhost on port 5000 via telnet (you can download and use PuttY if you don't have telnet installed), then that means that server isn't running.

If you're using a Windows machine, go to your package.json for the server that is running on port 5000 and change this line:

"start": "./node_modules/.bin/concurrently \"./node_modules/.bin/nodemon\" \"npm run client\"",

To this:

"start": "./node_modules/.bin/concurrently \"npm run server\" \"npm run client\"",

Watch your build messages and you should see something similar to the following:

[0]                                                                     

                                                        
            

Answer 3

I had a same problem in my React App and I fixed it by just adding "/" after the port number in package.json file (so now it's: "proxy": "http://localhost:5000/")

Answer 4

if you are not using concurrently at your server side then simply run each front-end and back-end separately such that server side should run first and client side last.

Answer 5

I have similar issue. The problem was that server was listening on ipv6 ::1 address and the proxy was connecting to ipv4 127.0.0.1

I changed both addresses from localhost to 127.0.0.1

Answer 6

In my case the problem was that I have been accessing the PORT by the wrong name, i had it PORT instead of SERVER_PORT which was my correct environment variable name. So this problem means that there is a something wrong in your code, in my case the port on which the server should be running was undefined.
