I have no problem receiving the payload via UDP, but the webhook isnt working. A got the initial message after enabling, but the message when the payload arrives works only one time

{
  "reports": [],
  "registrations": [],
  "deregistrations": [],
  "updates": [],
  "expirations": [],
  "responses": []
}
``

I use webhook.site for testing. Is there any know issue at the moment?
