The issue is with tcp timestamp. When I am disabling it, things are
working fine but when I enable the issue re-occurs. However, I am not
seeing tcp timestamps on packet, even when it is enabled simply
because my client doesn't support it.

But the question is, if I my client doesnt support timestamp , why
enabling timestamp on server side is creating an issue??
