Overriding `FLUXER_CLIENT_IP_HEADER_NAME` causing frontend to break due to 403 to RPC

Summary

When you override the FLUXER_CLIENT_IP_HEADER_NAME to anything other than x-forwarded-for the frontend stops working because all /rpc/internal returns a 403.

Steps to reproduce

  1. Go to docker-compose.yml
  2. Override FLUXER_CLIENT_IP_HEADER_NAME to something other than x-forwarded-for
  3. Run docker compose up -d --force-recreate api
  4. Run docker compose logs -f and try to access the app and observe the 403s appearing.

Environment

Dunno about version, whatever latest build was as of 1st July 2026, on Arch Linux.
