How to fix "+try-failover: New failover in progress" in Redis
Redis Sentinel logs "+try-failover: New failover in progress" when multiple failover attempts overlap, usually because a previous failover is still underway or quorum cannot be reached. This prevents duplicate promotions and ensures only one master election occurs at a time. To resolve, wait for the current failover to complete, verify Sentinel quorum and network connectivity, then retry if needed.

How to fix "CROSSSLOT Keys in request don't hash to the same slot (sharded pubsub)" in Redis
Redis Cluster returns `CROSSSLOT Keys in request don't hash to the same slot` when you attempt a multi-key operation (like MGET, MSET, or sharded Pub/Sub) on keys that hash to different hash slots. Redis Cluster partitions data across 16384 slots, and multi-key commands require all keys to map to the same slot unless you use hash tags. This guide explains slot hashing, hash tags, and how to structure keys or use client-side routing to avoid cross-slot errors.
