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

[AimbotNooby]

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.

[kazar4]

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

[DrNyk]

All I did was refresh the webpage. That's apparently not a graceful disconnect. So what is someone supposed to do if they want to reload the webpage?
