Setting up your Hippo application...
Setup failed! You will need to create the Hippo app manually.
The error was: Error: connect ECONNREFUSED 127.0.0.1:80

I can see it tried to contact localhost:80 but ... I never configured that so I don't know where it got it from. If it's possible to add more context into the error message that would really help with this error.

Oops, just realized that this is a duplicate of the problem from #39. When there is a problem parsing the URL provided, it seems to quietly default to 127.0.0.1:80 instead of yelling at me.

Yikes. Definitely time for a big error handling pass - this has been a neglected area I'm afraid. Thanks!
