Webhook not working

[Davidjus]

Hi,

I created an app that is working for few months already with the API Calls. Now I created an endpoint for webhooks and configured it in my app, but I'm not able to receive anything from hubspot.

In the webhooks label always appears as failed but without any specific error: 

Also, if I open it the information I have it is not too much:

If I copy the json, test it from Postman, or sending the post from other servers it is worked as expected.

At this point, I don't know how to continue.

The unique thing that can be "strange" is that our client uses the port 443 for other services and the webhook is on port 8443 so the url for the webhook is something like this: https://url:8443/connector/webhook.  ¿Can this be the reason why it is not working?

Thanks in advance,

David

Considering you both were working with a webhooks question recently, wonder if you could help here?
