WebSocket Connection Doesn't Even Last 5min

[AbdallahR99]

when reverse a websocket connection it doesn't last few minutes then disconnect, how to set the websocket timeout?
in the ASP.NET when I do a reverse proxy for a websocket then try to extend its connection duration I got the ActivityTimeout option

what's equal to ActivityTimeout here?

You will need to make your clients ping the server periodically to keep the socket alive.
