Bug Report

Description

Bug Summary:
The logout URL is not using WEBUI_URL.

Steps to Reproduce:
Set the environment variable WEBUI_URL=https://example.com. Sign into Open-WebUI and then sign out.

Expected Behavior:
The URL after logging out should be WEBUI_URL/auth (e.g. example.com/auth).

Actual Behavior:
The URL after logging out is WEBUI_URL:{reverse-proxy-port}/auth/ (e.g. https://example.com:2828/auth/).

Environment

Open WebUI Version: v0.1.125
Ollama (if applicable): N/A
Operating System: Debian GNU/Linux 12 (bookworm) / Docker version 26.1.3, build b72abbb
Browser (if applicable): Chromium v125.0.6422.60 and Safari v17.5

Reproduction Details

Confirmation:

I have read and followed all the instructions provided in the README.md.
I am on the latest version of both Open WebUI and Ollama.
I have included the browser console logs. N/A
I have included the Docker container logs. N/A

Installation Method

services:
  open-webui:
    container_name: open-webui
    hostname: open-webui
    image: ghcr.io/open-webui/open-webui
    restart: on-failure
    volumes:
      - /apps/Open-WebUI/data:/app/backend/data
    environment:
      - TZ=America/Edmonton
      - ENABLE_IMAGE_GENERATION=True
      - ENABLE_LITELLM=False
      - IMAGE_GENERATION_ENGINE=openai
      - OPENAI_API_KEY=my_key
      - WEBUI_SECRET_KEY=my_secret
      - WEBUI_URL=https://example.com
    networks:
      - reverse_proxy

Additional Information

I have an nginx-proxy that routes https://example.com to Open WebUI. It's a slightly customized version of nginx-proxy. It works by having my router forward WAN_IP:443 to SERVER_IP:reverse_proxy_port (which is 2828), which is Nginx that forwards to http://open-webui:8080.

I have dozens of containers that have no problem with this, so it's interesting that Open WebUI has figured out the reverse_proxy_port of 2828, unless that's just coincidence. In any case, it should respect WEBUI_URL verbatim (including port, which is implied as 443 since the protocol is https) when it's defined.
