When I try to install Discourse, I get this error every time:
DNS:
_I’m using CloudFlare_
I have searched many posts here but have not found a solution (that works for me).
I installed Apache2 because it runs the normal website.

The issue is probably happening because of cloudflare proxy. You’ll have to disable cloudflare optimization by clicking orange cloud and making it grey on the DNS page in cloudflare for the given (sub)domain. If you’d rather have cloudflare, You’ll need to edit the configuration file manually to disable the discourse built in ssl.

It should be immediate in most cases byt you can wait ~5 minutes after changes to be extra safe. You can ping your domain and as soon as it starts replying from your VPS IP address instead of cloudflare IP, you should be good to go.

Discourse need credentials for a SMTP (email) server in order to be able to send emails. More information about this is available here:

Then you can’t use `discourse-setup`. Have a look at [How to set up Discourse on a server with existing Apache sites](https://meta.discourse.org/t/how-to-set-up-discourse-on-a-server-with-existing-apache-sites/30013)

I got it working. I set Apache’s ports to 2053 and 444, which only required me to configure Cloudflare’s entries with ports using Portzilla and I was able to use `discourse-setup`.
