Original GitHub issue: https://github.com/open-webui/open-webui/issues/16549

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

0.6.22

Ollama Version (if applicable)

Operating System

Ubuntu 24.04.03

Browser (if applicable)

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

Display the interface

Actual Behavior

Crashes

Steps to Reproduce

• Have an API endpoint not responding
• Cry

@quadeare commented on GitHub (Aug 13, 2025):

I'm experiencing the same issue. My OpenWebUI instance crashed after my PVC ran out of disk space.

Now, the front-end UI is stuck in a loop, and the back-end is returning an error.

If you have a workaround, I would greatly appreciate your help!

I connected to the docker using VS code and edited main.py at line 1320 using the fix I liked earlier.
Then rebooted the container and I had access to the app ;)

@QDUCHENNE Thank you for your response!

Unfortunately, with a Kubernetes deployment, the situation is a bit more complex. I need to create a specific volume or a ConfigMap to overwrite this file. Another option would be to modify the entrypoint to address the issue in main.py.

I plan to create a new image that incorporates your fix, and I'll wait for an official resolution.
