            **"Please set your API key" message**
            - Check that you added the API key secret in Space settings
            - Verify the secret name matches your configuration
            - Ensure your OpenRouter account has credits
            
            **Building Failed**
            - Check `requirements.txt` formatting (no extra spaces/characters)
            - Verify all required dependencies are listed
            - Try reuploading files if build gets stuck
            
            **Error 401 (Unauthorized)**
            - Invalid API key or incorrect secret name
            - Check OpenRouter account status and credits
            - Regenerate API key if needed
            
            **Error 429 (Too Many Requests)**
            - Rate limit exceeded
            - Wait a few minutes before trying again
            - Consider upgrading OpenRouter plan for higher limits
            
            **Access code not working**
            - Verify `SPACE_ACCESS_CODE` secret is set correctly
            - Check for typos in the access code
            - Case-sensitive matching
            
            **URLs not fetching content**
            - Check URLs are publicly accessible
            - Some sites block automated requests
            - Verify dynamic URL fetching is enabled if needed
