Change your preferred to "global availability". Round-robin will rotate between all pool members that are passing health checks. Global availability will return the pool member with the highest (closest to 0) order that is passing health checks. If no pool members are available for GA, then the LB method will try using the alternate method, and finally will fall to the fallback method.
