Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.6.31

Ollama Version (if applicable)

No response

Operating System

Linux+k3s

Browser (if applicable)

Chrome

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

There are repetitive errors and warnings related to OAuth; however, I was able to log in and use the app using OAuth authentication.

Actual Behavior

Repeatitive messages like the following.

Steps to Reproduce

Set up the openweb-ui container with OAuth support using OIDC.

    # oauth
    - name: WEBUI_URL
      value: https://openwebui.xyz.duckdns.org
    - name: ENABLE_OAUTH_PERSISTENT_CONFIG
      value: 'false'
    - name: ENABLE_OAUTH_SIGNUP
      value: 'true'
    - name: OAUTH_MERGE_ACCOUNTS_BY_EMAIL
      value: 'true'
    - name: OAUTH_SESSION_TOKEN_ENCRYPTION_KEY
      valueFrom:
        secretKeyRef:
          name: openwebui-oauth-secrets
          key: sessionTokenEncryptionKey
    - name: OAUTH_CLIENT_ID
      value: duck
    - name: OAUTH_CLIENT_SECRET
      valueFrom:
        secretKeyRef:
          name: openwebui-oauth-secrets
          key: clientSecret
    - name: OPENID_PROVIDER_URL
      value: https://xyz.cloud-iam.com/auth/realms/duck/.well-known/openid-configuration
    - name: OPENID_REDIRECT_URI
      value: https://openwebui.xyz.duckdns.org/oauth/oidc/callback
    - name: ENABLE_OAUTH_ROLE_MANAGEMENT
      value: 'true'
    - name: OAUTH_ROLES_CLAIM
      value: resource_access.duck.roles
    - name: OAUTH_ALLOWED_ROLES
      value: user
    - name: OAUTH_ADMIN_ROLES
      value: admin
    # end oauth

Additional Information

I don't fully understand how to use the ENABLE_OAUTH_PERSISTENT_CONFIG settings, so I set it to false.

I wonder if the error is related to the value in OAUTH_SESSION_TOKEN_ENCRYPTION_KEY. The key value is not some random string. It is a Fernet encryption key, but there's no mention of it in the document. I wonder if there are other hidden requirements of this key or other related settings that I didn't set correctly.

No. I thinks the doc says if I set OAUTH_SESSION_TOKEN_ENCRYPTION_KEY, I
don't need to set the web secret key. Also, the log says it generated one
on startup.

If I set the web secret key, do I need to reset the database?

@davidshen84
incorrect, the docs say that OAUTH_SESSION_TOKEN_ENCRYPTION_KEY defaults back to WEBUI_SECRET_KEY

It does not say you don't need to set the WEBUI_SECRET_KEY
In fact, the SSO tutorial page specifically says that WEBUI_SECRET_KEY is required.

Correction: The SSO Troubleshooting Tutorial says it, not the normal one. Updating the docs rn!

But the troubleshooting tutorial should have been conducted first before opening an issue

I have set both WEBUI_SECRET_KEY and OAUTH_SESSION_TOKEN_ENCRYPTION_KEY to the same value and still get this Error. The site still seems to be functional.

Perhaps it's related to my OIDC provider? I am using cloud-iam.com, which uses KeyCloak for its service.

I enabled the global debugging log, but I don't find anything useful.
Here's the full container log https://0x0.st/KBRE.log.

Is there any particular log or configuration setting you are looking for?

Also, I found the error did not occur right after I logged in, but after I
started a new chat session. The error log only occurred once, but the
warning log repeated.

Thanks

We're unable to reproduce here, are you able to provide any other relevant

<!-- gh-comment-id:3350003953 --> @davidshen84 commented on GitHub (Sep 30, 2025): I enabled the global debugging log, but I don't find anything useful. Here's the full container log https://0x0.st/KBRE.log. Is there any particular log or configuration setting you are looking for? Also, I found the error did not occur right after I logged in, but after I started a new chat session. The error log only occurred once, but the warning log repeated.

My provider is Microsoft.

The typo mentioned in https://github.com/open-webui/open-webui/issues/17585 - fixed in 0.6.32 - was intended to call get_server_metadata_url.

Per my tests with 0.6.32, get_server_metadata_url() is returning None which throws the error during _perform_token_refresh. Same error as the OP. My provider is microsoft.

I know this works instead of calling get_server_metadata_url - perhaps it may be of some use.

            token_endpoint = None
            try:
                metadata = await client.load_server_metadata()
                if metadata:
                    token_endpoint = metadata.get("token_endpoint")
                    if token_endpoint:
                        log.debug(f"Retrieved token endpoint for provider {provider}: {token_endpoint}")
            except Exception as e:
                log.error(f"Failed to load server metadata for provider {provider}: {e}")

Maybe an issue with specific providers?

Same issue here.

open_webui.utils.oauth:get_oauth_token:654 - No OAuth session found for user xxx, session yy

but only after some time (I suspect after access token expiry). I do NOT have any log entries from
open_webui.utils.oauth:_perform_token_refresh

Yes, secret keys are set. Will keep monitoring and try the fix mentioned above.

Issue Report:
This issue still seems to be persisting. I’m currently running the latest dev build. However, when my token is close to expiring and I trigger a tool that relies on it, the refresh process fails with the following errors:

I was having exact same issue and errors in the log using Microsoft provider as well.

The issue appears to be that

self.get_server_metadata_url(client_id) returns None?, and throws this exception at

08f8713ee1/backend/open_webui/utils/oauth.py (L477C15-L479C24)

I haven't dug into root cause of that yet, but hard coding it to 'https://login.microsoftonline.com/{mytenantid}/v2.0/.well-known/openid-configuration' resolves the issue.

maybe this should be getting it from OPENID_PROVIDER_URL, but isn't?

Leaving this here if anyone else faces the same problem:

I installed Open-Webui using the helm chart and enabled pipelines. After disabling pipelines everything works as expected. As I currently do not need pipelines, I did not investigate further, why this occurs, but I think it has something to do with how OPENAI_API_BASE_URLS is used in combination with OPENAI_API_KEY.
