I'm sorry to hear that you're experiencing issues with your bot. It sounds like there might be a problem with the assistant's ability to execute functions or make external calls. To assist you better, I'll need to check a few things:
1. Has there been any recent changes to your server or network configuration that might be blocking outgoing calls?
2. Can you confirm that the assistant's configuration, including any API keys or endpoints, is still correct and hasn't expired or changed?
3. Is there any error message or status code that the assistant provides after attempting to use the function?
Once we have more information on these points, we can proceed with troubleshooting the issue. If you have already checked these and everything seems in order, please let me know so we can explore further steps to resolve the problem.
