Socket hangup when using TLS in Hapi server - node.js

Question

Whenever the server starts, I see the following console error message:
Server started at: https://localhost:3333
170929/232536.579, [log,connection,client,error] message: socket hang up, stack: Error: socket hang up
at TLSSocket.<anonymous> (_tls_wrap.js:829:25)
at emitOne (events.js:95:20)
at TLSSocket.emit (events.js:182:7)
at Socket.<anonymous> (net.js:484:12)
at Socket.g (events.js:273:16)
at emitOne (events.js:90:13)
at Socket.emit (events.js:182:7)
at TCP._onclose (net.js:484:12)
I was able to determine that if I removed the tls option from the server.connection, the error disappears.
This is the code in the server
import Hapi from 'hapi';
import inert from 'inert';
import fs from 'fs';
import { apiRoutes } from './api/api-routes';
import { serverConfig } from 'common';
import _ from 'lodash';
const good = require('good');
const server = new Hapi.Server();
const tls = {
key: fs.readFileSync('cert/server-key.pem'),
cert: fs.readFileSync('cert/server-crt.pem'),
ca: fs.readFileSync('cert/ca-crt.pem'),
};
const host = serverConfig.host;
const port = serverConfig.port;
server.connection({
address: '0.0.0.0', // listen on all interfaces!
host,
port,
tls,
});
const options = {
reporters: {
myConsoleReporter: [{
module: 'good-squeeze',
name: 'Squeeze',
args: [{ log: '*', response: '*' }],
}, {
module: 'good-console',
}, 'stdout'],
myFileReporter: [{
module: 'good-squeeze',
name: 'Squeeze',
args: [{ ops: '*' }],
}, {
module: 'good-squeeze',
name: 'SafeJson',
}, {
module: 'good-file',
args: ['./hapi.log'],
}],
},
};
server.register([
{
register: inert,
},
{
register: good,
options,
},
],
(err) => {
if (err) {
throw
// define static ui
server.route({
method: 'GET',
path: '/{path*}',
handler: {
directory: {
path: serverConfig.staticAssetsDir,
},
},
});
// start server
server.start(() => {
console.log(`Server started at: ${server.info.uri}`);
});
}
);
What could be the issue, and how could I get started debugging this?
