target url is working locally but after deployment the target server returns 417

Hi There,

I'm running to some weird issues, I have setup a node server to use http proxy middleware and it's working locally but after deployment to another server it returns 417,

const proxy = createProxyMiddleware({
  logLevel: 'debug',
  target: process.env.XXXX,
  changeOrigin: true,
  onError(err, req, res, target) {
    console.log(err, target);
  }
});

export default proxy;

Anyone has any idea?

To add more context on this: When I sent a request directly to from my server to target server it's working properly, but when I sent request from client to my server and from there to target server that doesn't work.

You can try v3@beta.

You should be able to get better debug and log data.

createProxyMiddleware({
   logger: console
})

# enable debug logging
DEBUG=http-proxy-middleware* node app.js
