WebSocketServer java.io.EOFException

java.io.EOFException is an exception thrown by java I/O when an end of file or end of stream has been reached unexpectedly during input. In the context of a WebSocketServer, this error could occur if the connection between the server and client is closed unexpectedly, such as when the client terminates the connection.

To troubleshoot this issue, you can try the following steps:

1. Check the logs to see if there are any error messages or stack traces that might provide more information about the cause of the exception.
2. Ensure that the client is not terminating the connection unexpectedly. You can do this by checking the client-side code and ensuring that it is properly closing the connection when it is no longer needed.
3. Check the server-side code to ensure that it is handling WebSocket connections correctly and not prematurely closing the connection.
4. Make sure that your WebSocket server implementation is compatible with the WebSocket protocol version used by the client.

If none of these steps resolve the issue, you may need to seek additional help or consult the documentation for your WebSocket server implementation to see if there are any known issues or troubleshooting steps specific to that implementation.
