/portal/*=loadbalancerprod The uriworkermap.properties file is correct - workers are correctly sent to it assuming all the workers are accessible.
The problem is when the workers in the load balancer are being initialized, if one worker is not available, the load balance worker is considered not valid. Because its not valid, requests will not be sent to it. This does not seem to be the desired behavior of a load balancer.
