Installation or Upgrade Fails with a Load Balancer
Timeout Error
A vRealize Automation installation or upgrade for a distributed deployment with a load balancer fails with
a 503 service unavailable error.
Problem
The installation or upgrade fails because the load balancer timeout setting does not allow enough time for
the task to complete.
Cause
An insufficient load balancer timeout setting might cause failure. You can correct the problem by
increasing the load balancer timeout setting to 100 seconds or greater and rerunning the task.
Solution
1 Increase your load balancer timeout value to at least 100 seconds.
2 Rerun the installation or upgrade.
