ERR_TLS_CERT_ALTNAME_INVALID

[coderpradp]

Expected behavior

I'm supposed to get the request via proxy

Actual behavior

I'm getting ALTNAME error

Setup

• http-proxy-middleware: 0.17.4
• server: express + 4.15.2
• other relevant modules

proxy middleware configuration

function relayRequestHeaders(proxyReq, req) {
    Object.keys(req.headers).forEach(function (key) {
        proxyReq.setHeader(key, req.headers[key]);
    });
};

function relayResponseHeaders(proxyRes, req, res) {
    Object.keys(proxyRes.headers).forEach(function (key) {
        res.append(key, proxyRes.headers[key]);
    });
};

const options = {
	target: 'example.com',
	logLevel: 'debug',
	onProxyReq: relayRequestHeaders,
	onProxyRes: relayResponseHeaders
}

server mounting

var app = express();

app.use('/apps', proxy(options));
app.listen(3000);

When ever I add changeOrigin: true I get 404 errors. Any help?

[robertwbradford]

@coderpradp Did you ever figure this out?

Getting same error when proxying request to a ssl based server

[alexichepura]

Had same issue.
Added changeOrigin to fix this and pathRewrite to fix 404

  const apiProxy = proxy('/api', {
    target: API_ENDPOINT,
    changeOrigin: true,
    pathRewrite: { '^/api': '' }, // remove leading /api to match real API urls
  })

perfect, thank you @alexichepura

What location is this file found at?

[dardino]

I have already set changeOrigin to true.
I think that the error came from a self signed certificate.
then:
how to accept SELF SIGNED certificate in dev environment?

it seems to be enough to set secure: false

[bhushan-patil-official]

This solution works while I am accessing a secure ip from the localhost using http-proxy-middleware although, is there anyway we can provide the self signed ssl certificates to from the frontend to bypass it?

[chimurai]

You can try the ssl option.

Here is an example:

A test https server I was trying to proxy to was using a self signed certificate, I found that by striping all the request headers seemed to allow it to successfully connect and return a response.

I changed the relayRequestHeaders function to this;

function relayRequestHeaders(proxyReq, req) {
  Object.keys(req.headers).forEach(function (key) {
    // strip all the request headers, as the receiving server is freaking out on one of them
    proxyReq.setHeader(key, '');
  });
}
