title: VCR is returning UnhandledHTTPRequestError
body: <p>I have a site that can save links submitted by users. The create action takes a url, and pulls data from the og:tags in the html. The app itself works fine, but I'm having trouble testing it in RSpec with VCR. </p>
  
  <p>The test passes fine without VCR, but takes very long (the actual code has multiple HTTP requests). 
  When I try to run my test with VCR, I get the following error. How can I fix this issue?</p>
