server not found: no server available #205

I'm using Redis in cluster mode.

Some write commands fail with the following error

java.lang.RuntimeException: server not found: no server available

I have also faced the same issue , the workaround is to give actual endpoint of nodes like List(RedisHost("redis-public.cache.amazonaws.com", 6379), RedisHost("redis-public.cache.amazonaws.com", 6379) ) its with play redis but here the main issue is that if any proxy is available in between( through haproxy ) then it is not working getting same error . any suggestion will help !!!

It caused by filtering available redis host with cluster map. here

My recommendation is to use direct redis address instead of hosts.
