Check Existing Issues

I have searched for any existing and/or related issues.
I have searched for any existing and/or related discussions.
I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
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)

lmsysorg/sglang:nightly-dev-cu13-20260401-b6fe0cca

Operating System

Ubuntu 24.04.2 LTS

Browser (if applicable)

Chrome 146.0.7680.164

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 running openwebui on an Ubuntu server using Docker, the results should be consistent regardless of which network port is used for access

Actual Behavior

The data corresponding to /chat/completions is SSE stream data, but the page parses it as JSON

Steps to Reproduce

多网卡环境，分别使用不同局域网ip访问
Ubuntu 24.04.2 LTS
docker: 29.3.1-1
ghcr.io/open-webui/open-webui:main

That's a web socket error. The second image you show is when the client was unable to make a proper websocket connection due to network issues network limitations or other error.
