Hi all, I have implemented subscriptions, locally, they work fine. However, on

now

, I am currently getting this issue when running a subscription in the playground on the now server:

{
  "error": "Could not connect to websocket endpoint <wss://xxx.now.sh/>. Please check if the endpoint url is correct."
}

two weeks ago, everthing worked fine with now. Any thoughts, how this could have happened? Did now upgrade something?
