"BrokenPipeError: [Errno 32] Broken pipe" when reloading client webpage

Hi, when I reload or close my client page the following Error comes up.
Btw, I have a loop in my function, which is called when a message is received.
An similar error is coming on windows: #110

BrokenPipeError: [Errno 32] Broken pipe

I tried solving it by following this Webpage, but now another error occurs.
Backend terminated or disconnected. Use 'Stop/Restart' to restart.

Broken pipe errors occur when a connection is lost. It's a normal error if you don't disconnect gracefully.

Is there a way to handle this for connections that don't disconnect gracefully? Like a way to check without it crashing
