How can I fix this AsyncioWebSocket "RuntimeError: Event loop is closed" issue?

[c00kiemonster]

I setup a Flask instance using AsyncioWebSocket websockets and implemented the echo example. It works completely fine, I can send and receive websocket messages just fine without any error messages on neither browser nor server side.

But if I leave it for a like 5-10 minutes and then load the echo example again I get these error messages below all of a sudden.

How can I fix this issue?
