Problem with domain name deploying on DigitalOcean with mupx

I deployed an app to DigitalOcean using mupx. At the time, I didn’t have the real domain set up so I configured it to use a temporary domain like I used that domain in the mup.json and the nginx site conf file.

Once I got the real domain,, I changed the configuration and deployed. If I go to the app comes up however, if I view the page source I see

<frameset rows="100%,*" border="0">
  <frame src="" frameborder="0" />
  <frame frameborder="0" noresize />
<!-- pageok -->
<!-- 02 -->
<!-- -->

I double-checked the configuration and I don’t see a reference to anywhere. Any ideas why it’s loading that?

Also, why is the site loading in a frameset? Is that the expected behavior? First time deploying a Meteor app so I’m not familiar with that.

Turns out it was related to “domain masking”
