Google analytics/Meteor and Modulus

I am having a hard time getting the spiderable package to work in my meteor app hosted on a modulus servo. I have install the ongoworks:spiderable and added this line to my modulus env vars -METEOR_PKG_SPIDERABLE_PHANTOMJS_ARGS = --ignore-ssl-errors=yes --debug=true
and I was getting the error -
spiderable: phantomjs failed at https://mysite.com/: null and once I added the above code I stopped getting that error, but when I use an online tool It doesnt find the site.

Is anyone familiar with getting this working on modulus and also does anyone have a good suggestion on how I can check if my site is crawlable?
