API Error After Recent Update – Anyone Else Experiencing This?

I’m testing an application that uses the OpenAI API, and after making a few requests, I started seeing unexpected behavior. Some requests occasionally fail even though the same payload worked earlier.

Has anyone experienced intermittent API errors or inconsistent responses recently? If so:

What error code are you seeing?
Did you identify the cause?
Were there any changes that helped resolve the issue?

I’d appreciate hearing about your experience or any troubleshooting tips.
