When I'm starting my rails application now I'm unable to view the app on localhost:3000 instead I now have to use 127.0.0.1 which theoretically is the same. But I seem to get errors because of it, such as:

Request origin not allowed: http://127.0.0.1:3000

now I ran sudo nano /etc/hosts to check my hosts and localhost is set up to be 127.0.0.1 so I'm finding this strange. The localhost just shows a blank page.

Does anybody have experience fixing this issue?

  • Are you using ActionCable? Perhaps this will answer? [Request origin not allowed: http://localhost:3001 when using Rails5 and ActionCable](http://stackoverflow.com/questions/35188892/request-origin-not-allowed-http-localhost3001-when-using-rails5-and-actionca) – Matouš Borák Apr 01 '16 at 10:01
