VIP not responding

I have configured a VIP on port https and backend server listening port 1062 and working fine.

 

Recently added another server and disabled thereafter changed the VIP port as any, unfortunately couldn't connect.

 

Checked the tcpdump logs, VIP is sending (R) reset packet.

 

Let me know how to troubleshoot further.

    The question is why did you change the virtual server port?

     

    WHY IS THERE SO MANY PEOPLE WHO WANT TO CREATE VIRTUAL SERVER LISTENING ON ANY PORTS?

     

    Do you configure a single back end application listening on any ports? Obviously NO!

     

    When you change port to ANY, virtual server property Port Translation is unchecked --> the client side destination port is used to open connection to pool member!
