how-to DEBUG mode investigate connection issues

Nobody has claimed this yet.

Migrating from native "amqplib": "^0.5.2" to log4js.
Getting error on the connection socket.
We have ssl enabled and process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

```
ERR { Error: Socket closed abruptly during opening handshake
ERR at Socket.endWhileOpening (/app/node_modules/amqplib/lib/connection.js:260:17)
ERR at Socket.emit (events.js:203:15)
ERR at endReadableNT (_stream_readable.js:1129:12)
ERR at process._tickCallback (internal/process/next_tick.js:63:19)
```

the config.rabbit is:
```
var rabbit = {
type: '@log4js-node/rabbitmq',
host: '127.0.0.1',
port: 5672,
username: 'guest',
password: 'guest',
routing_key: 's.system.log',
exchange: 's.exchange.infrastructure.logger',
mq_type: 'topic',
con: {heartbeat: 30, protocol: 'amqps'}
}````

Start with the RabbitMQ configuration and the amqplib stack trace at node_modules/amqplib/lib/connection.js:260. Reproduce the SSL connection attempt using the shown host, port, and protocol, then trace the opening-handshake failure and document the configuration or connection change that resolves it.
