Phantom JS Karma runner connects but doesn't execute tests in C9.io - karma-runner

Question

I followed the directions as per the Karma website to run Karma in the Cloud9 IDE (http://karma-runner.github.io/0.10/plus/cloud9.html)
my karma.config correctly contains:
hostname: process.env.IP,
port: process.env.PORT,
runnerPort: 0,
my terminal output:
Running "karma:test" (karma) task
INFO [karma]: Karma v0.10.10 server started at http://0.0.0.0:8080/
INFO [launcher]: Starting browser PhantomJS
WARN [launcher]: PhantomJS have not captured in 60000 ms, killing.
INFO [launcher]: Trying to start PhantomJS again.
I am able to see the words "Karma starting..." at
http://..c9.io/
However, I receive the following error logged in my console:
Mixed Content: The page at 'https://test-raptoria.c9.io/?
_c9_id=livepreview24&_c9_host=https://ide.c9.io' was loaded
over HTTPS, but requested an insecure XMLHttpRequest
endpoint http://test-raptoria.c9.io/socket.io/
EIO=3&transport=polling&t=1426358810471-0'. This
request has been blocked; the content must be served over HTTPS.
Any ideas on how to fix this?? It seems like the requests are being blocked..
I've shared my workspace here:
https://ide.c9.io/raptoria/test
Thank you!

Answer 1

Could you try to change the request to socket.io to https? If that is not possible, Try loading the test-raptoria.c9.io with http instead of https.

Answer 2

I downloaded my entire workspace from test (without the data folder and dependencies), and created a new one called simple. I ran 'grunt test' again and it works. I must've corrupted my old workspace somehow.
Problem solved!
Thanks for helping me look into this.
