Unable to connect to Redis through redis-cli
I applied for Redis OSS caches, and I installed redis-cli on my EC2. I cannot connect to redis via the command line: redis-cli -h xxxkuzmtv.serverless.apse1.cache.amazonaws.com -p 6379. This command doesn't respond, it blocks the shell command line and there are no error messages. How can I solve this?

There are some points:
- Check if the security group on Redis is open for this EC2 host, port 6379 has to be open.
- Verify the subnet of the connection, for instance, your EC2 has to be in the same network as Redis.
- If you configure the Redis property 'Encryption in transit' equals Enabled you have to add to your command line the parameter --tls, like this example :
redis-cli -h redis-hostname.serverless.use2.cache.amazonaws.com -p 6379 --tls
No error message means that packages can not reach the target at all
- check the Security group of the Elasticache instance (Incoming port 6379 from your EC2 security group or IP address)
- check NACL if EC2 and Elasticache are located in different subnets
- if EC2 and Elasticache are located in VPCs, configure VPC peering and routing between them as well as NACL and Security Group rules
