I recently added a shard to my cluster.

Everything seems to work, but the logs of the primary configserver show errors like:

2018-01-24T09:28:33.125+0100 I ACCESS [conn21] Unauthorized: not authorized on config to execute command { find: "shards", readConcern: { level: "majority", afterOpTime: { ts: Timestamp 1516782507000|4, t: 5 } }, maxTimeMS: 30000 }

Do I need to restart the config servers or the mongo routers after adding a shard to the cluster?
