Invalid IP error when login attempt fails, and netbox is behind reverse proxy (haproxy)

[pelinche]

Deployment Type

Self-hosted

NetBox Version

v3.7.4

Python Version

3.11

Steps to Reproduce

I'm running netbox using a docker image, and netbox is running behind a reverse proxy (haproxy). When the user tries do login on netbox, system give this error.

If password is correct, system works correctly and allow user to use system.

When i try to open netbox without reverse proxy, system gives me the right error message.

I tried a solution, changing the order to resolve IP Address (

netbox/netbox/utilities/request.py

Line 8 in f563ba7

def get_client_ip(request, additional_headers=()):

), and this solved for me.

Something upstream is setting HTTP_X_REAL_IP to a domain name rather than an IP address.
