Do you have a firewall that may be blocking them?

Does that domain name resolve directly to the vm?
Hmm. It looks like you’ve got discourse running there but there is some other problem now?

Because you didn’t resolve your connectivity issue.
The reason `discourse-setup` will fail if connectivity isn’t working is because let’s-encrypt will fail to enrol a certificate. You get a finite number of tries to do this per week.
You need to resolve the connectivity problem before you rebuild your instance.

What did you change?
I’m getting an “oops” page, suggesting that Discourse is running but that there is a problem, perhaps with the database.

I just downloaded the Discourse with ./launcher rebuild app ?
