Symptoms

Oracle Traffic Director is configured to proxy requests to a pool of origin server with ssl enabled. The origin server pool configuration is as follows: 

       <origin-server-pool>

          <name>finance-https</name>

    <type>http</type>

   <origin-server>

        <host>x.x.x.x</host>

       <port>8463</port>

    </origin-server>

</origin-server-pool>

 When accessing application via OTD the request fails with 503 error in the access log:

x.x.x.x - - [11/Sep/2018:16:35:04 +0000] "GET / HTTP/1.1" 503 244 -

x.x.x.x - - [11/Sep/2018:16:35:36 +0000] "GET / HTTP/1.1" 503 244 -

x.x.x.x - - [11/Sep/2018:16:35:40 +0000] "GET / HTTP/1.1" 503 244 -

The server.log shows the all the origin servers in the pool are offline:
