"client not initialized" error when using SSMCache with AWS elasticache autodiscovery

I am using Spring cache with AWS elasticache provider. I get this warning:

WARN c.g.code.ssm.spring.SSMCache - An error has occurred for cache defaultCache and key

I am using the same memcache without spring cache and it works fine. I get this error only when I use spring cache.

I have verified that the security groups has the Inbound port specified and I am running my code on EC2.
