ElastiCache - Redis Cluster mode enabled fails to write data in-between - redis

Question

I am using a redis cluster of node type m5.4x large with 1 node , in-order to cache some results. The writes to this redis node is very frequent. And I could see that intermittently the writes to cluster fails.
Below is the stack trace we see in logs for the failure.
org.redisson.client.WriteRedisConnectionException: Unable to send

I am using redisson client version 3.6.5.
Can someone please help me to identify what is the issue?
