Cookie persistence is not working correctly

We have a virtual server in a lower environement configured with a cookie profile and oneconnect the same as we have it setup on our prod boxes. We have a test site that allows us to choose with webserver we connect to as well as see which we connect to once connect. When we select a server, it takes 60 seconds or more to ever switch over. From there it is "sticky" but again, if we try to force it to the other server (there is only two) it takes at least anotehr 60 seconds or more to do so.

I have had a ticket in with support for a week now with no progress, does anyone know anything I can check to fix this issue??

Thank you!
