this is aws redis cluster. it used Encryption in transmission.

stanley23 commented 2 years ago

because i can't get info about tls-client-key-file，tls-client-cert-file，tls-server-key-file，tls-server-cert-file，，，

bjosv commented 2 years ago

Have you tried to add rediss:// like -redis.addr rediss://test-redis-cluster-0001-002.test-redis-cluster.nyau2z.apne1.cache.amazonaws.com:6379 ?
