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

Hey Everybody,
I’m having the same issue
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.
```
Hostname for your Discourse? [discourse.example.c]: community.innovationdrive.c
Email address for admin account(s)? [me@example.com,you@example.com]: omar@innovationdrive.c
SMTP server address? [smtp.example.c]: smtp.sparkpostmail.com
SMTP port? [587]: 587
SMTP user name? [SMTP_Injection]: SMTP_Injection
SMTP password? [pa$$word]: ******************************
Optional email address for setting up Let's Encrypt? (ENTER to skip) [me@example.com]: omar@innovationdrive.c
```
Thank you in advance for all your generous help 😀

What happens when it builds?
Does the domain resolve to the IP of your host?
