Hi,

I have created a new droplet “Discourse-beta-ubuntu”, then I connected to the Droplet with Putty (root - password) and Discourse’s setup is started.

But setup doesn’t work:

Ports 80 and 443 are free for use
'samples/standalone.yml' -> 'containers/app.yml'
Found 1GB of memory and 1 physical CPU cores
setting db_shared_buffers = 128MB
setting UNICORN_WORKERS = 2
containers/app.yml memory parameters updated.

Hostname for your Discourse? [discourse.example.com]: forum.mywebsite.eu

Checking your domain name . . .
WARNING:: This server does not appear to be accessible at forum.mywebsite.eu:443.

A connection to http://forum.mywebsite.eu (port 80) also fails.

This suggests that forum.mywebsite.eu resolves to the wrong IP address
or that traffic is not being routed to your server.

Google: "open ports YOUR CLOUD SERVICE" for information for resolving this problem.

If you want to proceed anyway, you will need to
edit the containers/app.yml file manually.
Discourse is now installed.  Log into your admin account in a browser to continue
configuring Discourse.

I have bought the domaind from register.it and added to Cloudflare. I have changed only DNS, to redirect to Cloudflare.
