Diagnostics & Resolution

  1. Validate LLM Credentials:
    • In Stores > Configuration > Webkul > AI ChatBot Configuration, click the Validate LLM button under the LLM Provider group.
    • Confirm that a success confirmation is returned.
  2. Check API Quota & Rate Limits:
    • Verify that your AI provider account (OpenAI, Gemini, Anthropic, OpenRouter) has an active billing account with sufficient API credit balance.
  3. Verify Dedicated / Node Server Endpoint:
    • If using Pre Configured Model or Node Server, confirm that the endpoint URL is accessible from your Magento server and that firewall/security groups allow outbound port communication.
  4. Inspect Magento Error Logs:
    • Check var/log/system.log and var/log/exception.log for connection timeouts or authentication failures.
