When Load Balancer Node 1 is down or not reachable, unable to log in to Load Balancer Node 2.

Problem

You cannot log in to Load Balancer Node 2 when the Load Balancer Node 1 is down. Here are the steps:
  • Deploy a VMware Pulse IoT Center instance with Virtual IP and Load Balancer High Availability.
  • Stop the Load Balancer Node 1.
  • Try to login to Load Balancer Node 2.

Cause

When the Load Balancer Node 1 is shut down or the services are down, its consul is not up. This condition breaks the consul cluster and makes the consul in Load Balancer Node 2 as non-functional.

As a result, when you try to login to the Load Balancer Node 2, it fails as the consul is down.

Solution

This is a known limitation of the system.
