MOVED redirection loop detected with AWS Elasticache redis

Getting following error:

org.redisson.client.RedisException: MOVED redirection loop detected. Node redis://xxxxx-cache-0001-001.xxxxx-cache.yyyyy.usw2.cache.amazonaws.com:6379 has further redirect to redis://xxxxx-cache-0001-001.xxxxx-cache.yyyyy.usw2.cache.amazonaws.com:6379

We are using redisson 3.13.4 ( tried with 3.13.6 also) with AWS Elasticache Redis. For our internal testing we created AWS Elasticache Redis cluster with following configuration: Shards: 1 replica: 1 Engine compatibilty: 5.0.6 readMode=MASTER.

Connecting to configuration endpoind. In the error you see ‘redis://’ but we are using ‘rediss://’ , there is another bug in RedisException where ‘redis://’ ( without extra ‘s’) is hardcoded.

It was working fine till last week.

After further investigation, we found that problem was in our configuration. We have support for both clustered and non clustered mode. Configuration which causes the switch was changed incorrectly, because of which AWS Elasticache redis cluster configuration endpoint was getting used with ‘ReplicatedServersConfig’ instead of ‘ClusterServersConfig’.

Good thing I guess is, through this ticket, ‘redis’ vs ‘rediss’ scheme related issue got fixed.

Thanks for your help, appreciate quick responses on this ticket.

Could you share log with logging level = ‘TRACE’ for org.redisson package?
