Seeing 2 SYN-ACKS coming from Server for a single ACK from Client

Hi,

I am seeing a weird behavior where my client sends a ACK to start a TCP connection. In return gets 2 SYN-ACKS with 2 different ACK numbers.

Do you mean "my client sends a SYN to start a TCP connection"?

Can you share a capture with the packets at issue?
