Trying to start phpDeamon. It seems to work.

telnet 127.0.0.1 8047
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
quit
400 Bad Request

<html><head><title>400 Bad Request</title></head><body bgcolor="white"><center><h1>400 Bad Request</h1></center></body></html>Connection closed by foreign host.

But we can’t run a single example from the site (of those that we could find) that would make it work

writes Firefox cannot establish a connection to the server ws://127.0.0.1:8047/

Tell me and explain at least theoretically how the site and the server should interact in this regard
