Hi,

If possible perform on BIG-IP:

tmsh reset-stats net rst-cause

watch tmsh show net rst-cause

Then try to initiate connection to VS and observer results of watch command - which reason has counter increase?

What can be seen on client side of VS? Can you perform trace - maybe client connecting to VS is sending RST?
