elasticache redis not responding to redis-cli commands

I have set up elasticache with redis and the host is rechable which I can confirm with telnet, when Redis commands are issued it does not return any result, either with ubuntu@ip-10-0-2-8:~$ redis-cli -h master.xxxxxx-xxxx.xxxxx.xxxx.cache.amazonaws.com -p 6379 INFO or telnet and very unfortunately AWS cant show you redis logs

It's actually simpler than that and you don't need to disable Encryption-at-transit as suggested. Just use the --tls option along with the command as shown in the picture.

redis-cli -h --tls

The redis-cli client does not support SSL/TLS connections. To use the redis-cli to access an ElastiCache for Redis node (cluster mode disabled) with in-transit encryption, you can use the stunnel package in your Linux-based clients. The stunnel command can create an SSL tunnel to Redis nodes specified in the stunnel configuration. After the tunnel is established, the redis-cli can be used to connect an in-transit encryption enabled cluster node.

So you can either use stunnel or disabling in-transit encryption.

You need to add firewall rule to allow other machine to access your redis server. I meant you need to enable firewall rule to allow 6379 port accessible from outside. Following article will will help you to do this. Also please make sure redis is running on port 6379 or some other port.
