Target Server 503 Service Unavailable

Google Cloud Apigee
1

This question has been asked before in many different variations by other people but they are either unanswered or do not fit my situation.

I have set up a named target server using the Management API. A GET request gives me these details:

{
  "host": "httpbin.org/get?show_env=1",
  "isEnabled": true,
  "name": "httpbin",
  "port": 443,
  "sSLInfo": {
    "ciphers": [],
    "clientAuthEnabled": false,
    "enabled": true,
    "ignoreValidationErrors": false,
    "protocols": []
  }
}

In my API proxy, control reaches the intended target endpoint and I have this code which references the named target server:

<HTTPTargetConnection>
   <LoadBalancer>
      <Server name="httpbin"/>
   </LoadBalancer>
   <Path/>
</HTTPTargetConnection>

However, I get a 503 Service Unavailable error. The request never leaves my API proxy according to Trace. Below is a screenshot just after my target request postflow from Trace:

If it helps, replacing the code in my API proxy with:

<HTTPTargetConnection>
   <URL>https://httpbin.org/get?show_env=1</URL>
</HTTPTargetConnection>

works completely fine.

Hi Edward, This might solve your problem

While creating target server give the host name without path:

“host : httpbin.org”

In proxy modify the target reference with “path” element:

  <HTTPTargetConnection>
   <LoadBalancer>
      <Server name="httpbin"/>
   </LoadBalancer>
      <Path>/get?show_env=1</Path>
</HTTPTargetConnection>
