Your front-end HTTP proxy config (Apache or Nginx) is incomplete - it's not proxying the hostname and port which the client supplied.

There are working configs you can copy here: https://github.com/netbox-community/netbox/tree/master/contrib

With Apache you're likely missing the ProxyPreserveHost On setting. I don't know about Nginx.

It's just when I'm in the rack, the system is normal.

[candlerb]

That's correct.

Most hyperlinks that Netbox generates are relative, so don't care what the hostname is. But in a few places, such as rack elevations, the hyperlinks are absolute: in those cases, the Netbox (gunicorn) server needs to know what hostname you were accessing, in order to generate the correct hostnames in those links.

(I believe this is so that if you copy one of these images and use it somewhere else, the links will continue to work)

If I put the IP works, but the images do not appear. Why is localhost defined.

If I put the IP works, but the images do not appear.

Most likely the image links point to http://localhost/ as well. You can use your browser's console to inspect the HTML.

Why is localhost defined.

I assume you mean "why does Netbox generate links to localhost"?

It's because your front-end proxy (Apache or Nginx) is configured to forward incoming requests to localhost:8001, and if you don't configure it to pass on the hostname from the original request, then Netbox thinks your browser asked for "localhost:8001", so it builds absolute links starting with http://localhost:8001/

The problem you have is one I've seen several times before, and the solution is what I already gave you.
