0.1.11 caused fatal error: socket hang up

[asujata]

The latest update to 0.1.11 caused my existing proxy setup to fail with "fatal error: socket hang up".

My setup:

proxies: [
          {
            context: '/api',
            host: '...',
            port: 443,
            https: true,
            changeOrigin: true,
            xforward: false,
            rejectUnauthorized: false
          }
        ]

The error only occured when trying to use https.

Switching back to 0.1.10 resolved my issue.

Same bug hit me. As soon as SSL comes into play connections fail. Pinning to 0.1.10 still works.

[rpocklin]

Ouch! Same problem, glad there's a workaround.

[zhukov]

Same for me. I see the request response in browser, but nginx says that there was a plain request over SSL port. Downgrading to 0.1.10 with npm install grunt-connect-proxy@0.1.10 solved the problem.

[zourtney]

I just encountered this same error...and burned quite a bit of time tracking it down! Downgrading to 0.1.10 worked for me as well.

[ghost]

Had the same error, after debugging forever - downgraded to v0.1.10 :(

[lostthetrail]

Also experiencing this. Downgrading to 0.1.10

[seglo]

I believe it has something to do with the upgrade to the 1.x.x branch of http-proxy. grunt-connect-proxy 0.1.10 is using "http-proxy": "~0.10.3". There's a lot of rewritten work in the 1.x.x branch so it's hard to be any more specific on what the cause might be.

[seglo]

I've resolved this issue in my own plugin (grunt-connect-prism) by handling the new error event in http-proxy 1.x.x. I was able to reproduce the bug using a user's codebase, but I haven't figured out how to write a test for it. If someone using grunt-connect-proxy who can reliably reproduce this issue wants to try out my fork and confirm whether or not it works for them, then I'll submit a PR.

@seglo sadly your fork doesn't work for me.

[seglo]

@rbrcurtis Thanks for trying. Is your project on github or can you provide me with a reliable way of reproducing the issue?

[rbrcurtis]

Its not unfortunately (work project). Its not doing anything special though; your fix handles the errors but what I think might be happening is that grunt-connect-proxy isn’t handling ssl on the target correctly.

I’ll dig into it more tomorrow when I have time and if I can’t figure it out I’ll work up an example project for you.

@rbrcurtis Is the server you're proxying using HTTPS? I think grunt-connect-proxy is incorrectly mapping the https option to the secure option in node-http-proxy. The secure option isn't used to determine if the target is https, it's used to determine whether to validate certs or not. If your https is self-signed try setting this to https to false.

[rbrcurtis]

my local server is not https, but the remote servers I’m proxying to are all https. They’re all on amazon and are not self signed. I tried setting https to false and still get socket errors on latest and {"error":"proxy_error","reason":"read ECONNRESET”} on your fork.

[jox]

We're having the "Fatal error: socket hang up" on some rest api that runs on port 8080 with "https: false". Strangely it helps to change the api and proxy settings to another port (e.g. 8082).

Another phenomenon is that some in our team are having this issue and some not. I myself never had it until today. Now I also changed the port to 8082 and it works again.

We're using grunt-connect-proxy 0.1.11.

[ciglesiasweb]

I have the same situation as jox. Fortunatelly I realize the day before I installed express for testing purposes and that destroyed my workspace. The solution was: unistalling node and reinstall...

[procyborg]

absolutely. reverting to 0.1.10 suppresses the socket-hangup bug. i am proxying a https endpoint for oauth2. thanks for the pointer guys.

[ihr]

I can confirm that changing the port worked for me. Here is relevant part of my Gruntfile.js:

proxies: [
                {
                    context: ['/api'],
                    host: 'localhost',
                    port: 8090,
                    https: false,
                    rewrite: {
                        '^/api': ''
                    }
                }
            ]

I'm having a problem with secure WebSocket connections over the proxy (HTTPS->HTTP). Normal websocket connections work fine in my app. So I thought I'd debug the wss case and wrote a WebSocket test for it. I decided to go simple and started off with just normal ws:// connections.

However, even that didn't work since I got slapped in the face by this "fatal error: socket hang up" bug, so now I'm stuck with no working websocket connections over the proxy whatsoever (even though they work in my browser). Changing ports doesn't seem to work and in 0.1.10 the tests won't even run. I've tried to dig in to http-proxy also, but to no avail.

The branch with the websocket test is here https://github.com/Flexim/grunt-connect-proxy/tree/wss if you're interested in debugging it with me.

[xiaoshao]

I have the same problem in 0.1.11. I have two proxies as follows. { context: '/google', host: 'google.com', port: '80', rewrite: { '^/google': '', } }, { context: '/baidu', host: 'baidu.com', port: '80', rewrite: { '^/baidu': '/', } } the proxy for google works well. but the proxy for baidu doesn't work.

[ianblenke]

I'm having the same "Fatal error: socket hang up" problem with https proxy. Using http works just fine. Reverting to 0.1.10 doesn't seem to help. Would love to turn up the debugging here to understand what the problem may be. Any hints as to how to accomplish that?

[ianblenke]

Correction: reverting to 0.1.10 did work, I had to clean out the newer node_modules version first.

[dzdrazil]

I'm also having this problem on 0.2.0 (win8, node 0.12.2); reverting to 0.1.10 did work for me as well.

[lostthetrail]

I confirm this is still happening on 0.2.0

[mteodori]

same issue here, and the servers I am proxying to have valid certificates, not self-signed ones, the only solution is to stick to grunt-connect-proxy@0.1.10 and block it via npm shrinkwrap --dev
