Webhook not reaching the server after moving server.

[Remie_Malik]

We have a private app and we register some webhooks with the api. When i call the endpoint that lists the webhooks we get the 2 registered webhooks. 

But when we create an order and mark it as paid no webhooks are called. 

When we manually call the url. It reaches our server. 

I tried creating the webhook in the settings. And pressed the "Send test notification" button. But the call never reaches our servers access.log. 

We have recently been moving our apps to a new server and i think we still have DNS problem. Can anyone here help me with this? Am i missing something? 

From my browser the app is reachable. And we changed the DNS Monday 15:00 GMT +1 so that is more then 24 hours ago.

If you need anymore information please let me know!

Thanks in advance!

I turns out our certificate was not set correctly. 

In the afternoon we received a automated mail from Shopify which stated:  "certificate signed by unknown authority"

We had to add a chain file to our certificate. That fixed the problem for us immediately.
