Subject: [PATCH] Fix nil pointer dereference in socket server close method

- Added nil check for s.engine before calling Close() to prevent runtime panic
- Resolved issue where a nil pointer dereference occurred when closing the socket server
- This fixes the error: "runtime error: invalid memory address or nil pointer dereference"
