It looks like this instance is behind CloudFlare, was it installed that way?

Turn off the orange cloud and try again in five minutes.

Was this a fresh server, or was something already installed there?

Did you follow the [standard install](https://meta.discourse.org/t/142537?silent=true)?

On the same FQDN? with Let’s Encrypt enabled? Did you hit the [rate limit](https://letsencrypt.org/docs/rate-limits/)?

But what happened after you did that, because you were definitely not still seeing that Cloudflare error then?

That, and you still have Cloudflare enabled with the orange cloud.
