sxcooler opened a new issue #1236: GET /v4/default/registry/instances ... Connection was closed
URL: https://github.com/apache/servicecomb-java-chassis/issues/1236
 
 
   There's a lot of this log in my production: 
   ```
   2019-06-05 11:50:21,689 |-ERROR[registry-vert.x-eventloop-thread-0] LINE: 95 TraceId:- ServiceName:- in org.apache.servicecomb.serviceregistry.client.http.RestUtils : GET /v4/default/registry/instances?rev=865440c1754ef7dfe66be741a48e22ee6e8a5ecc&appId=risk&global=true&serviceName=risk%3Alai2-risk&env=production&version=0.0.0%2B fail, endpoint is service-center:30100, message: Connection was closed
   ```
   And finally it turns out like this:
   ```
   2019-06-04 14:09:25.302 WARN 1 --- [io-8888-exec-32] o.a.s.bizkeeper.BizkeeperHandler : bizkeeper execution error, info=cause:InvocationException,message:InvocationException: code=490;msg=CommonExceptionData [message=Cse Internal Bad Request];cause:CseException,message:No available address found. microserviceName=lai2-user, version=0.0.0.0+, discoveryGroupName=0.0.0.0+/empty/empty/instancesAll/
   ```
   Then my gateway got "Forwarding error" and my in-app invocation got errors (because the registry of instances may not be there)
   I tried this:
   ```
   servicecomb:
     ...
     request:
       timeout: 30000
   ```
   But some of the services goes well and some other didn't work!
   Could anyone plz dig into it to find the real reason?
