Pow port proxying doesn't work with Rails 5

I'm have a Rails 5 app running with Foreman and I'm trying to use Pow's port proxying to reach it. When I try to access my app at myapp.dev I get the following error:

Proxy Error

Couldn't proxy request to localhost:4000.

Error: connect ECONNREFUSED

I confirmed that the problem is specific to Rails 5 by generating a fresh app that runs Rails 4 and an app that runs Rails 5. Port proxying works with the Rails 4 app but not with the Rails 5 app.

To be more specific about the version, I'm using Rails 5.0.0.rc1.

I'm not sure if this is a problem with Rails or with my Pow configuration and would appreciate some insight.

Solution

  • Rails 5 with Puma no longer listens by default on 0.0.0.0.

    So starting your rails server with the option -b 0.0.0.0 should allow Pow to reach it.

    Too bad Pow does not seems to be maintain anymore.

    Edit:

    For those who don't want to deal with a command option, you can trick the server options by modifying the config/boot.rb file.
