I'm using the serverless API for a custom image classification task and get the results by sending a webhook URL with a secret in the API call. That worked perfectly well till a few days ago. Now it doesn't work anymore for some reason. I have logging inside the handler function which prints out the webhook URL as received by runpod. I can just copy it and call it with my browser. (It obviously wont work because I'm not sending the right data but I clearly see the try to call the endpoint logged in my backend). So I know that works.
But I don't see ANY connections being made from runpod at all in the logs! As if they get stuck somewhere before even reaching my backend. And I cant really debug it.
Is there any issue with that currently? Or does someone have an idea for what the reason could be?
