Check Existing Issues

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

Installation Method

Docker

Open WebUI Version

0.6.16

Ollama Version (if applicable)

0.9.0

Operating System

Ubuntu 22.04.5 LTS

Browser (if applicable)

140.0.4

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

Open WebUI should load the GUI interface in the browser after typing the URL / submitting the login form.

Actual Behavior

Open WebUI shows an endless loading animation and throws an error in the JavaScript console.

Steps to Reproduce

  1. Install Open WebUI 0.6.16.
  2. Create a user account.
  3. Open "Settings" > "Tools" and successfully add a MCP tool server (e.g. https://example.com/openapi.json).
  4. Shutdown the running MCP tool server so that connections to it don't get a response.
  5. Reload the GUI of Open WebUI in the browser.

If the MCP tool server is running, the Open WebUI GUI loads as expected.

Logs & Screenshots

The JavaScript console throws an error:

TypeError: NetworkError when attempting to fetch resource.
BKankAwn.js:58:5665
