Pushnotification

Yesterday I updated a Connections environment to the latest CFix. In other environments I found that PushNotification Cluster was not started after the update, like described in the knowledge base document PushNotification broken after upgrading to CFix.65CR1.2201. In this update the application and cluster were running, but not working at all. Browser console.log showed the error: Error connecting to push auth sync service /servic/info: RequestError: Unable to load https://cnx-fqdn/push/service/info status: 500
