I am trying to get the example located here to work. I have this on an Ubuntu server with apache 2.4.41 and PHP 7.4.3. I start the sample server using
./websocket-server.php tcp://192.168.2.162:9001
and it starts fine. Then on a client machine in the same subnet, I call the html page that is included with that sample and it connects
I have tried it on websocket.org and it works as well.
When I open another ssh session with the server and run tcpdump, I can see the connection happened and that every time I send a message there is an exchange between the client and the server. These are the 2 packets after I click send on the client.
tcpdump: listening on any, link-type LINUX_SLL (Linux cooked v1), capture size 262144 bytes
18:37:45.863086 IP (tos 0x0, ttl 64, id 55343, offset 0, flags [DF], proto TCP (6), length 70)

The problem I have is that the client(s) never receive anything from the server and the only thing firing on the server is that the client is idling. It seems that the server can see the client connecting but it never sees the incoming message, or the event handlers are not registering? Is anyone familiar with a working example of websockets and the Fat Free Framework?
Any guidance is appreciated
