Original GitHub issue: https://github.com/open-webui/open-webui/issues/15688

Check Existing Issues

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

Installation Method

Git Clone

Open WebUI Version

0.5.2

Ollama Version (if applicable)

latest

Operating System

MacOS Sequoia 15.5 (24F74)

Browser (if applicable)

Arc, Chrome, Firefox (all)

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

Using the chat for more than a few messages

Actual Behavior

Chat endpoints stop functioning (return 403 forbidden for each API request) after around 5-6 messages, in every chat, always - quicker if the messages are long.

Steps to Reproduce

Starting to use chat, after 5-6 messages the next POST request (for a submitted prompt) to {BASE_URL}/api/v1/chats/{CHAT_ID} results in Forbidden 403 and so does every subsequent API request

It seems like a restriction from your provider, perhaps a context limit, a speed limit, a timeout...

Unable to reproduce.

@rgaricano Thanks. Did you attempt to reproduce this with version 0.5.2 or latest?

I observe the same problem with all models (anthropic through custom functions, but also using openai v1 default API) and confirm it depends somehow on the overall context length, either responses will break after a few small messages or already after one large prompt. I am on the latest release running on ubuntu 22 within docker.
