I am using Pinpoint 3.0.1 and configured Redis to work on the same host as the Pinpoint Collector, without authentication. Despite confirming that Redis is up and running, I still get a RedisConnectionFailureException when starting the Collector. I am intentionally using Redis, unlike issue #11880, which discusses avoiding Redis.

application.yml

pinpoint:
  zookeeper:
    address: xxx.xxx.xxx.xxx
  metric:
    kafka:
      bootstrap:
        servers: xxx.xxx.xxx.xxx:9092

spring:
  pinot-datasource:
    pinot:
      jdbc-url: jdbc:pinot://xxx.xxx.xxx.xxx:9000
      username: xxx
      password: xxx

  data:
    redis:
      host: localhost
      port: 6379

I have not configured a Redis password, and verified the following:
Redis is running locally on port 6379.
No password is required (requirepass is not set).

Environment:
Pinpoint/collector version: 3.0.1

Please investigate why Redis authentication is being attempted even when no password is configured. Let me know if there is a workaround or patch needed for this version.

After switching to Redis version 6, the application is now running successfully without any issues. Thank you:)
