Netbox: Absolute URL points to wrong link in SVG rack view

[heiko-ma]

Environment

• Python version: 3.6.8
• NetBox version: 2.8.0

Steps to Reproduce

1. Disable any installed plugins by commenting out the PLUGINS setting in
   configuration.py.
2. Select a rack through navigation to Organization -> Racks -> the rack
3. Select any device by clicking on it

Expected Behavior

The properties of the selected device should be opened and I should be able to edit them.

Observed Behavior

Netbox is redirecting the request to 127.0.0.1:8001 instead of the URL used to access the site itself. Therefore the request can't be completed. This could be related to https://github.com/netbox-community/netbox/issues/4147

Workaround

Selecting the device through Devices -> Devices -> the device works because in this case, no absolute URL is used.

NetBox uses whatever host information gets forwarded to it from the HTTP frontend (e.g. nginx or Apache). It looks like your server isn't configured to forward this information. Check your configuration against the relevant reference configuration provided in contrib/. Please post to the mailing list if you need further assistance.
