I have setup the self-hosted Docker environment and enabled HTTPS using Let’s Encrypt following the tutorial.

It assumes prior installation without HTTPS enabled. person_raising_hand Required user level: System Administrator exclamation This guide is only for existing installs where HTTPS is not enabled. Following the [official setup guide](https://github.com/discourse/discourse/blob/main/docs/INSTALL-cloud.md) automatically enables HTTPS by default.

It always fails on the step below. Setup without HTTPS works fine and the forum is publicly available on HTTP.

It seems that ACME challenge is not accessible.

Did you read the first sentence in that guide that says that if you’re doing a [standard install](https://meta.discourse.org/t/142537?silent=true) you don’t need to follow that guide?
Is this a recent [standard install](https://meta.discourse.org/t/142537?silent=true)? Did you run `discourse-setup`?
It looks like you may have port 80 (and perhaps also port 443) blocked for incoming connections.

Oddly, the first works but the second doesn’t:
```plaintext
○ → curl http://discourse-test3.docentric.com/srv/status
ok
○ → timeout -v 5s curl http://discourse-test3.docentric.com/.well-known/acme-challenge/iEFjgyseuVL1IzIrTjmfhwv0HqV7EgUmQUVhy1nmnCE
timeout: sending signal TERM to command ‘curl’
```
I’m not sure what would cause that if it’s a standard setup.

It is an old test installation without HTTPS and now I would like to enable HTTPS.
I have tried to edit app.yml manually and also to run discourse-setup. In both cases the same error.
I have also tried to delete Discourse (containers and files) and install from scratch, but the result is the same.
I agree that it looks that port 80 in not available, but if I comment the following two lines in app.yml, the forum runs on HTTP without problem.
- “templates/web.ssl.template.yml”
- “templates/web.letsencrypt.ssl.template.yml”
Where on the disk are static files like [http://discourse-test3.docentric.com/.well-known/acme-challenge/iEFjgyseuVL1IzIrTjmfhwv0HqV7EgUmQUVhy1nmnCE](http://discourse-test3.docentric.com/.well-known/acme-challenge/iEFjgyseuVL1IzIrTjmfhwv0HqV7EgUmQUVhy1nmnCE)?

It has turned out that just ACME protocol was blocked on the company firewall. Now it works 🙂
