Also from the base.pp at the repository [1] there is no reference to 7811 and this is probably the https port as I can see from the exception.

Stratos Load Balancer 2. Nginx (via extension) 3. HAproxy (via extension) First you could try to run either of these against your Stratos deployment and see whether they are working as expected (before trying the puppet module). Load balancer only requires ActiveMQ and CEP information (IP, port) to run. Do a complete build and find 1 in the following folder: https://github.com/apache/stratos/tree/master/products/load-balancer/modules/distribution Update loadbalancer.conf and thrift-client-config.xml with the above values and start the product.

How we will subscribe the application we need to the load balancer and access the load balancer and redirect us to the multiple instances of the application above. Is there any guide we can use?
