Zuul Exception: Use instance of closed

[kenttanl]

In #2179， 'WCMIS208' instance is closed， but Eureka is in "self-preservation mode"， so it was not removed, but now， occasionally there will be such an exception:

...
org.apache.http.conn.HttpHostConnectException: Connect to WCMIS208:10015 [WCMIS208/10.16.72.21] failed: Connection refused
...

I think Zuul should skip instance of has been closed , or try again that until the encounter the healthy instance，so ， Is there such the function？ thank you

I stil dont know what you mean by "closed". Zuul can be configured to retry failed requests http://cloud.spring.io/spring-cloud-static/Dalston.SR2/#retrying-failed-requests

Sorry my English, "closed" that mean is "stopped". I will try to do it like this, and now I restarted the gateway, that to solved this problem.

I will try to add the config:

client.ribbon.MaxAutoRetries
clientName.ribbon.retryableStatusCodes

to see if will encounter this problem again.

Thank you very much, and sorry my English again
