Check Existing Issues

I have searched the existing issues and discussions.
I am using the latest version of Open WebUI.

Installation Method

Git Clone

Open WebUI Version

latest master

Ollama Version (if applicable)

No response

Operating System

Ubuntu 22.04

Browser (if applicable)

Chrome

Confirmation

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

When setting WEBUI_URL to "/desired-name", I want to be able to to load the application over my browser.

Actual Behavior

I can access my openwebui instance through https://domain.name/$(WEBUI_URL), but then None of static/, /_app/, manifest.json, /asset/... etc can be served properly, because it does not include $(WEBUI_URL)... I checked in vit.config.js, and svelte.config.js, and there is not such a thing that trigger WEBUI_URL (I'm not that much into .js/svelte/vite...)

Here was my nginx.conf:
location /$(WEBUI_URL){
proxy_pass http://domain.name:3000/;
# I tried different config, seeting the prefix in the header, without adding it, proxy passing to IP/DNS/ with and without /$(WEBUI_URL).
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_buffering off;
}

Steps to Reproduce

Ubuntu 22.04
Clone Repo
Change docker-compose.yaml -> WEBUI_URL to environment
Configure NGINX
Run it, and access https://d.n.s/WEBUI_URL
observe 404 on statics and so on
