Hello,
I have the same problem with nginx and discourse. Always getting the “welcome to nginx"-Page instead of discourse.
DNS and Mail server are setup and I’m hosting on-prem and not in the cloud.
I used this guide: https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md
Fresh installation from Ubuntu:

I also tried Debian 9 and 10.
I will also try Ubuntu 18.04LTS and write down the result
The server has access to the Internet, but is not accessible from the Internet and the DNS ends with .lan
Soo… does letsencrypt play a role at all, because authority can’t check it from the Internet?
I installed Ubuntu 18.04LTS and I have the same problem.

Discourse will not work from an IP address, you must own a domain name such as example.com to proceed.
If you’re not using a publicly valid FQDN then the normal install route won’t work for you. Local DNS entries and domain names aren’t interchangeable here. Let’s Encrypt will fail because the DNS entry isn’t valid.
You’re going to need to modify the app.yml by hand to eliminate HTTPS and Let’s Encrypt. Comment out the unnecessary templates and the entry which exposes port 443.
Unless you plan on issuing a self-signed certificate you will be serving everything over HTTP.
I have the same problem with Fun Tec. I have my own domain and I don’t think it is the problem of letsencrypt. Here is my logs after command sudo ./launcher restart app. Can you find some useful information?

I’m dealing with the same issue here.
Fresh install of ubuntu 24 lts
Bootstrap completes, then nginx default page.
When I ./discourse-doctor I get:

If the message is not delivered it is not a problem with Discourse.

And the test email arrives as expected.
I feel like I’m really close.

There is no nginx or apache2 for that matter installed on the server.
Just to clarify, it seems that nginx page is only available when surfing to the host name from the host computer, any other computers on the network just get a failed to connect error.
Yes ./discourse-setup is the bootstrapping sequence right? The container wouldn’t be running if I didn’t I don’t believe. I followed the instructions here, and about 7 minutes later I got the Welcome to NGINX page.
Is there a specific connection test you’d like me to run? There was so much output from the setup I couldn’t capture it all.
