Redis Cluster : Few hash slots are NOT reachable

[Guru Prasad]

Hi,

I have a created a redis-cluster on docker container (locally) with 3 master and 3 slave nodes. When I connect to the cluster from client, few keys get saved into cluster, but many requests failed due to below error. 

StackExchange.Redis.RedisConnectionException: Endpoint 172.18.0.6:6379 serving hashslot 72 is not reachable at this point of time. Please check connectTimeout value. If it is low, try increasing it to give the ConnectionMultiplexer a chance to recover from the network disconnect. 

Connection time out has been increased to 2.5 minutes. Also executed the "cluster meet" command on each ip and port. 

Please share your thoughts on fixing this.

P.S, C# Client using StackExchange.Redis library to connect with redis.
