connect ECONNREFUSED 127.0.0.1:3001

Hopefully this is a config issue - but am raising it, as am stuck.

I followed the README and created a github PAT and added it to a new .davidrc file.

`npm start` does start up the website - and it is able to retrieve latest updates from npm

BUT if I try to use a URL to view a particular package, there is an error reaching local port 3001

```
curl http://localhost:1337/alanshaw/grunt-jsio

Error

FetchError: request to http://localhost:3001/gh/alanshaw/grunt-jsio failed, reason: connect ECONNREFUSED 127.0.0.1:3001

```

1. Is there some config step I need to add?

2. which PAT elements need to be enabled? (github has a long list of permissions that can be enabled)

Thank you!
