    Hi madhava , 

    I see in the Pcap that no completed flow between client side and server side , Bigip Resets the connection when seeing the HTTP GET request , I see also this GET request maybe truncated , something corrupted in this Request and not follow the standard of http. 

    Please test the below steps : 
    1) change the standard http Virtual server to >>> Performance layer 4 , you have to remove http profile prior to changing the virtual server type. 
    Performance layer 4 Virtual server  means that >>> Bigip will forward all requests ( somehow acts as a router ) Not http Checks.

    2) repeat the Tcpdump command that I sent in the first reply , and upload it. 

    Let us see what will be the behavior and decide what is the suitable workaround for your issue. 

    Look forward to hearning from you soon 🙂
