For reference, the tests communicate over port 3001, and the default client-server communications are on port 3000. It looks like an old instance of mocha (jigg server + two jigg clients) was still left running and caused those two errors. If this is not the case, please follow up on this in a new issue.

Thanks for trying out JIGG!
