Not receiving webhook events for Avatar IV API

Hi team,

We're using the Avatar IV endpoint in our product, however since an hour of writing this post we're seeing the following problems:

The https://api.heygen.com/v2/video/av4/generate API doesn't resolve within 60 seconds resulting in timeouts. This is however intermittent.
We are not receiving any webhook events (avatar_video.success, avatar_video.fail) for the final video.

Is there an issue going on with the overall service? Is anyone else facing a similar issue?
