I've been struggling with this issue for a few days and can't figure out what's causing the problem. The test suite runs fine on TravisCI, and locally when I restart my computer. After doing something locally though, I keep getting the same error message:
Unable to load URL: http://localhost.dev:3001/en/users/sign_in because of error loading http://localhost.dev:3001/en/users/sign_in: Unknown error (Capybara::Webkit::InvalidResponseError)
Here is the full webkit-debug trace:

This comes up anywhere in the app that I try to visit a path. From what I understand, the "Unknown error" is from qt, not capybara-webkit, but I'm not quite sure who would be best to ask. I am using DNSmasq for subdomains and we have multiple languages so localhost:3000 is redirected to www.localhost.dev:3000/en.
Current versions of things:
Edit 1: Also posted on the capybara-webkit repo: https://github.com/thoughtbot/capybara-webkit/issues/667
Edit 2: Here is the test log file: https://gist.github.com/GolfyMcG/060053eba51a9ba69722
As I posted in the related Github issue, I found the solution here:
https://apple.stackexchange.com/questions/26616/dns-not-resolving-on-mac-os
Had nothing to do with Capybara-webkit and everything to do with how I had my ElasticSearch instance spinning up with testing.
