I have recently encountered an issue while using Visdom for data visualization, specifically receiving frequent WebSocketClosedError errors when attempting to send data to the client via WebSocket. The problem seems to arise when attempting to write a message to the WebSocket connection, only to find that the connection has already been closed. The detailed error trace is as follows：

Are there known scenarios or configuration issues that could lead to unexpected closure of WebSocket connections during data transmission?
Are there any recommended best practices or configuration adjustments to enhance the stability of WebSocket connections?
