Redis Cluster Support in Chirpstack

I am having issues connecting with the redis sentinel cluster. when I provide a connection string like: redis://:@:26379 I receive the error ERR Client sent AUTH, but no password is set. However, if I do not provide a password like redis://:26379 , then it is able to identify the master, but fails when trying to get keys with get keys error: NOAUTH Authentication required.

Any ideas? Seems sentinel doesn’t require a password to lookup master, but redis nodes require password.
