Duplicate of post at Unable to access preview site for testing my rails for ruby website, but seemingly important enough to warrant its own thread:
I’m having the exact same issue …and on three separate workspaces. It worked once, now it’s not working at all …even after trying the steps at https://docs.c9.io/docs/running-a-rails-app.
Are others having this issue?
And is there a workaround of some kind?
I’d really like to continue using c9…
