Symptoms

The steps to add a Load Balancer (running OTD) to an newly created SOACS instance prod_inst is being followed. This setup is working properly when accessing the SOACS instance via the OTD added from Oracle SOA Cloud Service Console.

Then another SOACS instance is created and let's call a qa_inst. The OTD created from above is re-configured to add a route to this qa_inst SOACS instance. After restarting the OTD, testing shows that the OTD fails to send requests destined to qa_inst instance. However the requests destined to the prod_inst are processed successfully.

The OTD log shows the origin servers in the qa_inst SOACS instance is unreachable:

[2017-05-04T02:05:25+00:00] [<HOST>-lb-1] [TRACE:32] [OTD-10962] [health-check] [pid: <pid>] trying to OPTIONS /, check-http-server reports: server <HOST>-wls-1:<PORT> server unreachable
[2017-05-04T02:05:25+00:00] [<HOST>-lb-1] [WARNING:1] [OTD-11016] [health-check] [pid: <pid>] , health-check reports: all servers in origin server pool <POOL> are offline.

The ping command is also used to verify network connectivity from the OTD VM to the qa_inst VM but it also fails. curl and wget issued from the OTD system are also unable to fetch content from qa_inst SOACS instance.
