title: Calling External/third-party URL via feignclient works, but results in warnings
body: <p>I am trying to use feignclient to call a third party url (sending notifications to android devices)</p>
  <pre><code>@FeignClient(value = &quot;external&quot;,url = &quot;${android.notification.url}&quot;)
  public interface AndroidNotificationClient {
  
      @RequestMapping( method = RequestMethod.POST, consumes = &quot;application/json&quot;)
      String sendAndroidNotification(@RequestHeader(&quot;Authorization&quot;) String auth, @RequestHeader (&quot;Sender&quot;) String sender,
                                                   @RequestBody String body);
  
  }
  </code></pre>
  <p>&quot;external&quot; is not defined anywhere - I was told that value is not used for any purponse.</p>
  <p>The API calls work, but I get warnings like</p>
  <pre><code>2022-05-10 07:52:17.015 WARN  --- [boundedElastic-1]  org.springframework.cloud.loadbalancer.core.RoundRobinLoadBalancer         : No servers available for service: fcm.googleapis.com
  2022-05-10 07:52:17.016 WARN  --- [androidNotification8]  org.springframework.cloud.openfeign.loadbalancer.FeignBlockingLoadBalancerClient         : Service instance was not resolved, executing the original request
  
  </code></pre>
  <p>The relevant portion of the properties file is reproduced below</p>
  <pre><code>feign.client.url=http://&lt;our_domain_name&gt;/api
  android.notification.url=https://fcm.googleapis.com/fcm/send
  android.authorization=key=xxxx
  android.sender=id=xxxxx
  
  
  
  eureka.client.serviceUrl.defaultZone=${EUREKA_URI:http://&lt;our_domain_name&gt;:&lt;port&gt;/eureka}
  eureka.instance.preferIpAddress=true
  </code></pre>
  <p>What am I doing wrong which is resulting in such warnings, and how do I remove them?</p>
