Issues connecting to ElastiCache Memcached

Question

I'm trying to connect to a ElastiCache Memcached endpoint through my EC2 instance, but I'm seeing this can't reach to the Memcached node:  
> telnet: Unable to connect to remote host: Connection timed out  
This just happening today. Is there some issue with ElastiCache?

Answer

Good, I restarted the memcached service into my web instance and worked again). The memcached service into my Bitnami instance allowes me to connect to ElastiCache.

Answer

Hi There,

When you get timeout issue, it is best to check the security group, NACLs of the Elasticache and EC2 for allowing the port ( in this case 11211 or the custom port, if configured ). Try with more than one EC2 instance to see if the issue is at EC2 or Elasticache side. Also, keep an eye on the Elasticache events to see if there is anything going on with the cluster.
