Not receiving Webhook URL - Failed to get API Key

Hi,
When trying to get webhook url I am getting the following message: "Failed to Get API Key. Service Connection error".

I have followed the steps of the following documentation:

https://academy.creatio.com/docs/8.x/no-code-customization/base-integrations/webhook-service-integration/retrieve-a-webhook

Is there something else I could be missing?
