Bug Report

Description

Bug Summary:
Frontend seems to fail because of the /itellm/api/v1/models timeout.

Steps to Reproduce:

Expected Behavior:
There shouldn't be any hard LiteLLM deps.

Actual Behavior:
After login page the screen is empty. Pending llm models api fetch, while the service has never started.

Environment

  • Open WebUI Version:
    0.1.121

  • Ollama (if applicable):

Why this is an enhancement and no bug related? That was working fine with 0.1.120.

Also I noticed that the issue is in fact not having a timeout. When I block the URI of that endpoint in browser the Frontend is rendering. So in fact it waits forever trying to fetch the data and blocks the rendering of the Frontend.
