Services occasionally are unreachable

skinny_1_1                     | 2019/03/13 02:40:34 Could not receive return actor object. Error: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp 192.168.208.16:1973: getsockopt: connection refused"
actors_service_1_1             | Actor requested for 8

In the above log, skinny fails to reach the actors service. I retried the request, and the actors service was reached fine. I have noticed this happen a lot with the recommended follows service (being failed to be reached from skinny), and I don't know what causes it, but waiting a while and retrying seems to work.
