Http2 module -> Chrome ERR_SSL_VERSION_OR_CIPHER_MISMATCH error

[meriturva]

Expected behaviour

Correct use of servermodule: https://github.com/nodejs/http2

Actual behaviour

No way

Environment Details

• Karma version: 1.7
• Windows 10

Steps to reproduce the behaviour

We have generated correctly self-signed certificated and we also tested with simple app:

'use strict';
let http2 = require('http2'),
fs = require('fs');

let options = {
    passphrase: 'xxxx',
    key: fs.readFileSync(__dirname + '/server.key'),
    cert: fs.readFileSync(__dirname + '/server.crt')
};

http2.createServer(options, function(req, res) {
    res.writeHead(200);
    res.end('Hello world over HTTP/2');
}).listen(3000);

Simple app works but when we use it with karma:

config.set({
       httpModule: require('http2'),  
       protocol: 'https:',
       httpsServerOptions: {
           passphrase: 'xxxx',
           key: fse.readFileSync(path.join(__dirname, '/server.key')),
           cert: fse.readFileSync(path.join(__dirname, '/server.crt'))
       },

Chrome browser just return error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH karma no error on console. I think that karma doesn't work correctly with http2 module (https://github.com/nodejs/http2). Am i right? any solution?

[meriturva]

I'm really sorry to write again here but we are blocked and we cannot pass to http2 protocol due to that issue. Any advice or workaround here?

Hello @meriturva ,

It looks we're on the same boat. Furthermore i can't make it work even with http1. Getting the very same issue of yours: ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

Did you, by any chance, found a solution?

[meriturva]

No! No solution found. I just keep http protocol for my tests and no speed up using http2

(caveat - it's late and this is doing my head in)

I didn't get this exact error but versions of node etc have moved on, but basically I too can't get http2 working, despite getting a 'test' server working as above.

I think createSecureServer should be being called in the karam web-server.js file but isn't. You can hack it by doing this in your karma config file though:

const http2 = require('http2'); http2.createServer = http2.createSecureServer;

Still doesn't work for me though, because of the proxy and not being able to translate between http1 and http2 header formats, so perhaps that too needs upgrading to http2-proxy.

It's a bit annoying as I've wasted probably 6-8 hours on this, assuming that it should be possible. The docs lead you to believe it but there's no working examples that I could find anywhere. Serving of the files is too slow and I may need to completely re-think my application testing strategy because of this :-(

Karma is unable to run Chrome with HTTPS. It is a big problem as I want to test browser APIs working only with HTTPS.

@martonx Running karma on https is not related to http2 module use. Look into the config option httpsServerOptions
