RedisException with message 'Redis server ha-sentinel-proxy:26379 went away

I'm using this package to work with sentinel in Laravel 9 but I'm having problems connecting to the master. I have three sentinel hosts. These hosts are always available using HAProxy. But right now when I want to connect to the master, I'm facing this error: "RedisException with message 'Redis server ha-sentinel-proxy:26379 went away'"

We are using Kubernetes and this is the result of telnet from one of the Laravel app pods to the sentinel (HAProxy):

$ telnet ha-sentinel-proxy 26379
Trying 10.104.11.114...
Connected to ha-sentinel-proxy.
Escape character is '^]'.

And this is the result of the telnet to one of the Redises from the same pod

$ telnet 192.168.23.131 6379
Trying 192.168.23.131...
Connected to 192.168.23.131.
Escape character is '^]'.

And this is the config value from here:

^ array:13 [
  "sentinel_host" => "ha-sentinel-proxy"
  "sentinel_port" => 26379
  "sentinel_service" => "master"
  "sentinel_timeout" => 0.2
  "sentinel_persistent" => null
  "sentinel_retry_interval" => 0
  "sentinel_read_timeout" => 0.0
  "sentinel_password" => "masked"
  "password" => null
  "database" => 4
  "serializer" => 1
  "cluster" => "redis"
  "parameters" => []
]

We can connect to the same sentinel service using predis and monospice/laravel-redis-sentinel-drivers. As you know monospice/laravel-redis-sentinel-drivers is not compatible with phpredis and Laravel 9.

Any suggestions? Thank you

seems like it was a config issue on Redis password, writing the issue here helped me find it
