Redis Sentinel 的 Redis cli 身份验证超时

问：

我在使用 Redis Sentinel 时遇到了问题。 我部署了 在我的 Kubernetes 环境中，bitnami 提供的带有 Sentinel 的 Redis HA 模式。 直到几天前，一切正常，我可以连接到 sentinel 容器和 redis。从昨天开始，我一直在日志文件中收到此错误，我正在使用的 redis 映像是 docker.io/bitnami/redis:7.0.8-debian-11-r0，而哨兵映像是 docker.io/bitnami/redis-sentinel:7.0.7-debian-11-r1009:04:32.67 INFO ==> about to run the command: REDISCLI_AUTH=$REDIS_PASSWORD timeout 220 redis-cli -h redis.gntn-bacheca-gad.svc.cluster.local -p 26379 sentinel get-master-addr-by-name mymaster

这是我正在使用的生成的 StatefulSet：

由于它之前工作过，我尝试从 kubernetes 中删除 Pod 并再次安装它们，但问题仍然存在。 这个问题可能是由什么引起的？
