incorrect TCP handshake In a typical TCP handshake, the process involves three steps: SYN: The client sends a SYN (synchronize) packet to the server to initiate the connection. SYN-ACK: The server responds with a SYN-ACK (synchronize-acknowledgment) packet to acknowledge the client's request and indicate readiness to establish the connection. ACK: Finally, the client sends an ACK (acknowledgment) packet back to the server to confirm the connection. If the remote server is not receiving the expected SYN-ACK response after sending the first SYN, it indicates a problem in the TCP handshake, which could be due to network issues, firewall rules, or other misconfigurations.
