after filling up all the information required by discourse-setup, gets this:
Sorry, these containers/app.yml settings aren’t valid – can’t continue!
If you have unusual requirements, edit containers/app.yml and then:
./launcher bootstrap app
Can you share your app.yml file please, removing/masking any passwords?
Or share what you typed in. Don’t include the password and user name, but note if they have special characters.

Please note I’ve changed the url to (.c) when they are really (.co) because Discourse won’t let a new user to post more than two links on this forum.
