What does this error signify?
```plaintext
Discourse version at discourse.jackrail.space: Discourse 2.7.0.beta1
Discourse version at localhost: NOT FOUND
==================== DNS PROBLEM ====================
This server reports NOT FOUND, but discourse.jackrail.space reports Discourse 2.7.0.beta1 .
This suggests that you have a DNS problem or that an intermediate proxy is to blame.
If you are using Cloudflare, or a CDN, it may be improperly configured.
```
I am running Discourse reverse proxied via nginx.

My understanding is that discourse doctor is limited to the vanilla install with internal nginx and somehow it can’t read the discourse version string when you’re using a reverse proxy with discourse. it isn’t something to be bothered about if you already know that you have a reverse proxy that is working fine. You can safely ignore this warning.

What problem are you trying to solve?

Non delivery of emails by Amazon SES. I am looking at _everything_, so I tried running the doctor.
Yes, my reverse proxy is running fine.

Then your can ignore that error.
