ERR_NAME_NOT_RESOLVED means the hostname cannot be resolved to an IP address by the DNS. If you look at the hostname ws-your-pusher-app-cluster.pusher.com, you can see that you should change the subdomain ws-your-pusher-app-cluster to whatever cluster your pusher app is located on. You can find the cluster in the Pusher dashboard.
