It seems like you've already taken some good initial steps by checking your OpenAI account, credit status, and generating new API keys. Since the error message indicates an issue with the API key or the request processing, let's go through a systematic approach to troubleshoot this issue:

1. Double-Check API Key and Endpoint URL: Ensure that the new API key is correctly entered into the configuration menu of the OpenAI Chatbot skill in ARC. Also, verify that the endpoint URL is correct and hasn't changed.

2. Check for Updates: Make sure that your ARC software and the OpenAI Chatbot skill are up to date. An outdated version might cause compatibility issues with the API.

3. API Key Permissions: On the OpenAI website, check if the API key has the necessary permissions and hasn't been restricted or limited in any way.

4. Network Issues: Verify that your computer has a stable internet connection and can reach OpenAI's servers. You can test this by trying to access the OpenAI API using a REST client like Postman with your API key.

5. Firewall or Antivirus: Sometimes, firewall or antivirus software can block outgoing requests. Ensure that ARC is allowed to communicate through your firewall or antivirus.

6. Error Logs: Check the error logs in ARC for any additional information that might point to the cause of the problem.

7. API Quotas: Even though you have credit, there might be a quota on the number of requests you can make within a certain timeframe. Check if you've exceeded this quota.

8. API Changes: OpenAI might have updated their API, and the skill may need to be updated to accommodate these changes. Check the OpenAI API documentation for any recent changes that might affect the skill.

9. Contact Support: If you've gone through all the above steps and the issue persists, consider reaching out to Synthiam support or the OpenAI support team for further assistance. While you mentioned that direct support contact is not your preferred method, they might have insights into recent changes or issues affecting the API.

10. Community Forum: Post a detailed question on the Synthiam community forum. Include the steps you've taken, the error message, and any relevant logs. The community or Synthiam team members might have encountered similar issues and could offer a solution.

Remember to make changes one at a time and test after each change to isolate the cause of the problem.

The latest update to the OpenAI ChatBot robot skill should give you a message that OpenAI has deprecated the legacy service endpoing. The suggested fix is for you to use the ChatGPT robot skill here: synthiam.com/Support/Skills/Artificial-Intelligence/OpenAI-ChatGPT?id=21559

@Athena please update your response.

Many thanks.

The ChatGPT robot skill gives this error when attempting to configure:

Can confirm that the error message now indicates the change.
