Websocket handshake response not forwarded from TCP to client
- by Saharsh
I am trying to create a websocket server. I can see the websocket client's opening handhshake. My response to it is received by the client laptop (I can see this on wireshark). So the TCP connection has been established. But the client (a chrome websocket client extension) does not receive the handshake packet. What could be a possible reason for TCP to not forward the handshake to the client or for the client to not be able to read the TCP message?
Client handshake:
