Proxy error: Could not proxy request /api/v1/products from
localhost:3000 to http://192.168.137.1:4000.
See https://nodejs.org/api/errors.html#errors_common_system_errors for more information (ETIMEDOUT).
this error keep on coming.
Frontend -> React
Backend-> Express, nodejs
I faced a similar issue but in the Mac machine. I changed localhost to 127.0.0.1 and that worked for me.
For Windows:
"proxy": {
"/auth/google": {
"target": "localhost:5000"
}
}
For Mac:
"proxy": {
"/auth/google": {
"target": "http://127.0.0.1:5000"
}
}
I just changed "proxy": "http://192.168.137.1:4000" to "proxy": "127.0.0.1:4000" and this worked for me now...
This is done on windows

I've created an API in nodejs backend and frontend I used reactjs as I've connected the api to my form
it shows the error
"Could Not proxy request"
Check what is the error in Chrome developer tools. It is most probably CORS issue.
If you are using NodeJs, you can use below command.
res.header("Access-Control-Allow-Origin", "*");
But this will allow CORS for all port running on your machine.
I faced the same issue when using express. I resolved it as shown below :
TRY THIS OUT IN YOUR PACKAGE.JSON CONFIGURATION refereed from create-react-app
"proxy": {
"/api": {
"target": "https://localhost:5002",
"secure": false
}
},
Also try add CORS configuration to your node check this video
I work on a project as a fullstack developer on using reactjs & express.
My express server is on server folder, and reactjs client is on server/client.
I set the following proxy at my package.json at my server/client folder which includes ReactJS (create-react-app based). :
"private": true,
"proxy": {
"auth/google": {
"target": "http://localhost:5000"
},
"/api/*": {
"target": "http://localhost:5000"
},
"/apis/*": {
"target": "http://localhost:5000"
}
},

When I connect to interent at the university campus I get the following error
but when I connect to internet outside campus no error happens. How can I avoid that from happening?
I really appreciate your help guys. I found that the issue is not related to university network restrictions. I found the main problem, is that express server is not working on the university network, so
npm run server which is "server": "nodemon index.js",
cause an error:
and that what searching for its solution now. You may help me on finding that even by linking to other posts resources.
I have a spring boot back-end api and I am trying to call a service for uploading or getting images from angular project. I have a standard proxy.conf.json file:
{
"/api": {
"target": "localhost:8080",
"secure": false,
"logLevel": "debug"
}
}
if my angular service is using Http(HttpModule) everything is ok, but since its deprecated and i want to do it the new way i am trying with HttpClient(HttpClientModule) but in log i am getting :
[HPM] Error occurred while trying to proxy request /upload/ from localhost:4200 to localhost:8080 (ENOTFOUND) (https://nodejs.org/api/errors.html#errors_common_system_errors)
and it is not working. On one try on a linux machine i got the same mistake but with (EINVAL). Can someone guide me what i am doing wrong ? Sorry if the question is stupid there are a few questions like this one but neither of their solutions does not seem to work in my case.
Try to set http protocol in front of the localhost link.
{
"/api": {
"target": "http://localhost:8080",
"secure": false,
"logLevel": "debug"
}
}
I created a new #angular/cli project and added one http GET call in the root component. Without using a proxy this works fine.
export class AppComponent implements OnInit {
constructor(private http: Http) {}
ngOnInit() {
this.http
.get('https://dog.ceo/api/breeds/list/all')
.map(response => response.json())
.subscribe(data => console.log(data));
}
}
When I try to add the configure as describe in the Angular CLI wiki things go wrong.
My proxy.conf.json file:
{
"/api": {
"target": "https://dog.ceo",
"secure": false
}
}
I changed the URL in the component to /api/breeds/list/all. And I ran ng serve --proxy-config proxy.conf.json
Then I'm gertting Internal Server Error message in my browsers console. And in the terminal where I started ng serve I'm getting this message [HPM] Error occurred while trying to proxy request /api/breeds/list/all from localhost:4200 to https://dog.ceo (EPROTO)
(https://nodejs.org/api/errors.html#errors_common_system_errors)
I have tried several other configuration options and multiple API's. Results are similar.
The complete code is available on GitHub: https://github.com/ErikNijland/angular-cli-proxy-test
Versions used:
#angular/cli: 1.3.0
NodeJS: v8.1.4
Note: I understand that #angular/cli is using Webpack. Which in turn is using http-proxy-middleware.
I think it is happening because of the origin your are asking https from http. This can be solved using a flag in your proxy.
{
"/api": {
"target": "https://dog.ceo",
"secure": false,
"changeOrigin": true
}
}
I have a simple web app built using the angular CLI. I want it to communicate with a backend using web sockets. I have the backend already written and have tested with a simple index.html page that the server can send and receive on sockets.
In my angular-cli project I have setup a proxy config file to setup a proxy to the backend.
proxy.conf.json
{
"/sock": {
"target": "http://localhost:3000",
"changeOrigin": true,
"ws": true,
"logLevel": "debug"
}
}
Then start the server with the following.
ng serve --proxy-config proxy.conf.json
For now I have a service that simply attempts to open a socket and send a fixed string which I'm expecting to see logged by the backend.
import { Injectable } from '#angular/core';
import * as io from 'socket.io-client';
#Injectable()
export class ChatService {
private socket: any;
constructor() {
this.socket = io({ 'path': '/sock' });
this.socket.emit('chat message', 'Hello World from browser!');
}
}
Note: I've had several go's at this with and without the /sock part of the url.
I start both servers. Get no console errors in the browser. But in the angular CLI web pack server I get the following messages.
10% building modules 2/2 modules 0 active[HPM] Proxy created: /sock -> http://localhost:3000
[HPM] Subscribed to http-proxy events: [ 'error', 'close' ]
[HPM] GET /sockjs-node/530/z1z3teld/websocket -> http://localhost:3000
[HPM] Upgrading to WebSocket
[HPM] Error occurred while trying to proxy request /sockjs-node/530/z1z3teld/websocket from localhost:4200 to http://localhost:3000 (ECONNRESET) (https://nodejs.org/api/errors.html#errors_common_system_errors)
Are web sockets supported or have I made a silly mistake?
Thanks
I managed to figure it out with a bit of trial and error. I looked at the console for the basic index.html page that works within the backend project. This backend project is basically the chat server demo application on the socket.io website. I noticed that when it opens up the web socket the url looks like the following:
http://localhost:3000/socket.io/EIO=3&transport=websocket&sid=wTvdQTclHXJSUmAmAAAA
So back in the angular CLI project I modified my proxy config to include the /socket.io/ part plus also added a wildcard.
{
"/sock/*": {
"target": "http://localhost:3000/socket.io/",
"ws": true,
"logLevel": "debug"
}
}
Bingo! Now when the service is constructed it opens the socket and emits a message which I can see logged in the backend.
