Websocket protocol error in WorkerMan. Is there a common error in it?

simple development instance HTTP protocol is normal, WebSocket protocol error is not recorded in "client connection failure reason"

WebSocket connection to "ws://127.0.0.1:2000/" failed: Connection closed before receiving a handshake response

I was told that php bug, do not use 7.3.0


workerman has video tutorials, which is pretty good. Web site: https://study.163.com/course/...
