301 redirect not working after editing app.yml file and rebuilding the app

Installation

I don’t get my old domain to redirect. I provide the entire app.yml (update to remove personal/private data).

## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

I checked it out after a successful rebuild. It just loads without any redirect. What is wrong with the code?

Note: the file “discourse_redirect_1.conf” wasn’t created in advance, should it?

I think that you can remove the after web config section. I believe it’ll do the redirect without it.

I think that there have been some changes to the nginx config since that code worked and that it now redirects everything to the Discourse hostname.
