Websockets in a cluster?

Question

Nginx

There are n-th number of servers that nginx stands in front of and distributes the load (round robin) on them.
Accordingly, when a request comes to the back of any server, after that, a push occurs, which is already distributed to any other server and, accordingly, there will be no push on the server where the back is.
Are there any ready-made solutions like Pusher or experience in creating your own pusher service?
