openclaw - 💡(How to fix) Fix [Bug]: Qwen OAuth refresh token expired or invalid - re-authentication failed since v2026.3.13 [5 comments, 2 participants]

Fix Plan

To resolve the issue with the Qwen model authentication, follow these steps:

1. Update OpenClaw: Ensure you are running the latest version of OpenClaw. You can check for updates by running openclaw --version and then updating if necessary.
2. Clear Authentication Cache: Sometimes, cached authentication tokens can cause issues. Try clearing the cache by deleting the .openclaw directory or the specific cache file related to Qwen authentication.
3. Re-authenticate with Code: After clearing the cache, re-authenticate using the command openclaw models auth login --provider qwenportal. When prompted, enter the code provided by the Qwen authentication webpage.
4. Check Terminal Output: After entering the code, check the terminal output for any errors or prompts that might indicate why the authentication process is not completing.

Example Code Snippets

If manual intervention is required to handle the authentication flow, you might need to modify the authentication script. Here's a basic example of how you could handle the authentication flow in a Python script using the requests library:

import requests

def authenticate_qwen():
    # Open the authentication URL
    auth_url = "https://qwenportal.com/auth"
    response = requests.get(auth_url)
    
    # Assuming the authentication code is provided in the response
    auth_code = input("Enter the authentication code: ")
    
    # Complete the authentication process
    complete_auth_url = f"https://qwenportal.com/auth/complete?code={auth_code}"
    response = requests.post(complete_auth_url)
    
    if response.status_code == 200:
        print("Authentication successful")
    else:
        print("Authentication failed")

authenticate_qwen()

Verification

To verify that the fix worked:

• After re-authenticating, check if the terminal proceeds past the "Starting Qwen OAuth..." step.
• Ensure that you can use the Qwen model without any authentication errors.

Extra Tips

• Regularly update OpenClaw and its dependencies to prevent similar issues.
• If the problem persists, consider checking the OpenClaw logs for more detailed error messages or seeking support from the OpenClaw community.
