TimeoutError: timed out during opening handshake

Additional Information

I am using the following jupyter command:

jupyter notebook --ip=0.0.0.0 --no-browser --allow-root --NotebookApp.token='' --NotebookApp.disable_check_xsrf=True

Both open-webui and jupyter run on same machine and are installed using python (pip)

Originally created by @ghost on GitHub (Mar 25, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/12052 ### Check Existing Issues - [x] I have searched the existing issues and discussions. - [x] I am using the latest version of Open WebUI. ### Installation Method Pip Install ### Open WebUI Version v0.5.20 ### Ollama Version (if applicable) _No response_ ### Operating System Windows 11 ### Browser (if applicable) _No response_ ### Confirmation - [x] I have read and followed all instructions in `README.md`. - [x] I am using the latest version of **both** Open WebUI and Ollama. - [x] I have included the browser console logs. - [x] I have included the Docker container logs. - [x] I have listed steps to reproduce the bug in detail. ### Expected Behavior The code should have been executed normally on clicking run. ### Actual Behavior It shows the following error: ``` Error: timed out during opening handshake ``` ### Steps to Reproduce 1. Generate a code using any model. 2. Click on "Run" 3. Wait for execution output. ### Logs & Screenshots Jupyter Logs: ``` [I 2025-03-22 22:37:35.321 ServerApp] User 987140793dfe407fa4741645782beddf logged in.
