To reproduce, start CueGlow Web-UI and open console. WebSocket will reconnect every 5 minutes with connection error popup always flashing up (on feature/patch-ui branch). This is standard behaviour for Javalin (javalin/javalin#119 (comment)).

To adjust, please see javalin/javalin#72 and https://javalin.io/news/2019/03/02/javalin-2.7.0-released.html and https://stackoverflow.com/questions/44882256/jetty-websocket-idletimeout.

Another option of course is to introduce keep-alive messages that get sent by the client.

Additional curious behaviour: The browser reconnects every 5 minutes, but the Cypress Instance reconnects every 2 minutes.
