no traffic after disable and enable pool members

Hi All,

 

During our testing, Server team disabled server and after some time they enable it. in F5 side server status as Green and we are able to ping and telnet. but no traffic on that particular node. we got traffic others pool members.

 

We are using TCP as Health Monitor. we ran tcpdump there is no handshake between Clinet to F5. Please advise on it.
