Hi
I did installed discourse many times. some days i do it a few times.
This time i installed discourse at f.example.LTD
i used servers from [Public Cloud: Cloud solutions and on-demand resources | OVHcloud Worldwide](https://www.ovhcloud.com/en/public-cloud/)
DNS cloudflare ( DNS only and `./discourse-setup` finds my `DISCOURSE_HOSTNAME` )
the error
> Discourse version at f.example.LTD: NOT FOUND
> Discourse version at localhost: NOT FOUND
happened when i kept the IP address and reinstalled the Ubuntu system to start fresh discourse.

as test i did install discourse on same server and Ip and point it to other subdomain and did work.
then i did [Change the domain name](https://meta.discourse.org/t/-/16098) and i back to the error
> Discourse version at f.example.LTD: NOT FOUND

So `f.example.LTD` resolves to your current server and you rebuilt?
Have you done many rebuilds so that you’ve hit let’s encrypt rate limits?
