Connection refused while trying "Run your first Node.js unikernel" guide

One I run unik build, it fails as I get the following:

jberi:testunik 🚀  $ unik build --name myImage --path ./ --base rump --language nodejs --provider virtualbox
INFO[0000] running unik build                            args= base=rump force=false host=localhost:3000 language=nodejs mountPoints=[] name=myImage path=./ provider=virtualbox
INFO[0000] App packaged as tarball: /var/folders/66/97n3236x5cq00vgfcj6cdsyc0000gn/T/sources.tar.gz.817030311
 
ERRO[0000] build failed: [cmd/build.go:105] building image failed: {[client/images.go:60] request failed: {[lxhttpclient/httpclient.go:339] error performing post request: {Post http://localhost:3000/images/myImage/create?base=rump&lang=nodejs&provider=virtualbox&args=&mounts=&force=false&no_cleanup=false: dial tcp [::1]:3000: getsockopt: connection refused}}}

I noticed that running unik daemon outputted INFO[0000] UDP Server listening on 0.0.0.0:9967, so I tried unik target --host localhost --port 9967 but same results.

My setup:
macOS High Sierra 10.3.3
VirtualBox 5.2.6 r120293
Docker 17.12.0-ce-mac49
Node v9.3.0

the unik daemon isn't running. are you sure that it's running?
if so, please paste the daemon logs here. you can get more verbose logs by running with unik daemon --debug

Answer 3 · 2018-01-28T17:55:28.000Z

it looks like the instance listener is up and running

Answer 4 · 2018-01-28T17:55:52.000Z

can you grab a screenshot of the instance listener vm logs?

Happy to, not sure how to exactly :)

Answer 6 · 2018-01-29T04:09:19.000Z

open up virtualbox -> click on the instance listener vm (VboxInstanceListener) -> show
then take a screenshit (e.g. with printscreen).

Was the gist what you needed? Anything I can provide to help diagnose?

Answer 9 · 2018-02-20T14:55:24.000Z

Encountering the same issue following the Java guide, any updates? :/

Answer 10 · 2018-03-14T02:34:48.000Z

Same problem here (tried same troubleshooting steps including changing the port to 9967 because I saw the same messages with the unik daemon)

unik master branch 56aac9e
MacOS X 10.13.3
NodeJS 8.4.0
NPM 5.3.0
VirtualBox 5.2.8
