When i disable the option http2 it works fine.
I am not quite sure if this an issue of transfer.sh, if it so tell me please then i'll report them the issue.

My configuration:

const proxy = redbird({
        port: 80,
        letsencrypt: {
                path: __dirname + '/certs',
                port: 9999
        },
        ssl: {
                http2: true,
                port: 443
        }
});

docker(proxy).register('CENSORED', 'dutchcoders/transfer.sh', {
        ssl: {
                letsencrypt: {
                        email: CENSORED,
                        production: true
                }
        }
});

Updating spdy to v4.0.0 fixes the issue: spdy-http2/node-spdy#343

Someone should close issues in this project. So many open issues which have actually been promptly resolved as this one should would send a better picture to new adopters like me.
