Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

ghcr.io/open-webui/open-webui:main

Ollama Version (if applicable)

n/a

Operating System

Ubuntu 24.04

Browser (if applicable)

Chrome 141

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

The OpenWebUI container should start successfully and make the web service available on port 3000.

Actual Behavior

The container starts successfully, stays healthy, and the TCP port 3000 is listening, but the web service does not open or respond in the browser.

Always shows:

CORS_ALLOW_ORIGIN IS SET TO '*' - NOT RECOMMENDED FOR PRODUCTION DEPLOYMENTS
USER_AGENT environment variable not set

Steps to Reproduce

  1. Run on Ubuntu 24.04.3 LTS with Docker 28.0.4
  2. Pull image "ghcr.io/open-webui/open-webui:main"
  3. Start container "docker run -d -p 3000:8080 -v open-webui:/app/backend/data --name open-webui ghcr.io/open-webui/open-webui:main"
  4. Check logs: docker logs -f open-webui
  5. See full Alembic migration chain and the warnings above.
  6. Stop/start container again → same result.

@silentoplayz commented on GitHub (Oct 28, 2025):

Nothing is actually broken here. The two messages you see are only warnings and the container is already past them and waiting for requests.

The first start of Open WebUI downloads some embedding models and can take 30-60 s on a slow link.

Once the embedding models have finished downloading, Open WebUI should be ready.
Because you mapped -p 3000:8080, open:

http://localhost:3000

in the same machine’s browser.

If you are on another machine use the host’s IP, e.g.:

http://192.168.1.42:3000

If the page still does not load:

  • curl -I http://localhost:3000 – should return HTTP/1.1 200 OK.
  • ss -tlnp | grep 3000 – make sure something is listening on 0.0.0.0:3000.
  • Check that no local firewall (ufw, nftables, cloud security-group) blocks the port.

If curl works but a remote browser fails, the traffic is simply being filtered outside the container; the OpenWebUI container itself is fine.

Hey, thanks for replying to this issue and confirming that nothing is broken.

I believe the container isn’t able to download the embedding models… Which models would those be?

Could you please clarify exactly which URLs or destination domains the container connects to during this process?

I’m setting up Open WebUI in a restricted environment with outbound traffic filtering, so I need to whitelist the endpoints.

Open WebUI tries to download sentence-transformers/all-MiniLM-L6-v2 as an embedding model from HuggingFace.
