When ElastiCache failover, it output the following error.

We are currently managing a queue using AWS ElastiCache for Redis and Laravel Horizon. When ElastiCache failover, most of the time it automatically switches to a new primary node. However, one time 3 months ago it didn't, and continuously output the following error.

Predis\Connection\ConnectionException(code: 0): Error while reading line from the server.

Predis\Response\ServerException(code: 0): READONLY You can't write against a read only replica.

ERR Error running script (call to f_230148430cb441a76f6486ae084405a674e00385): @user_script:two: @user_script: 2: -READONLY You can't write against a read only replica.

ElastiCache For Redis settings:

redis: 5.0.6
parameter group: default.redis5.0 (in-sync)

cluster mode: disabled
multi AZ : enabled
auto failover: enabled

Laravel Version:

config :

'redis' => [
    'client' => 'predis',
    'default' => [
      'host' => AWS Primary Endpoint,
      'port' => AWS PORT,
      'database' => 0,
    ],
];
'connections' => [
  'redis' => [
      'driver' => 'redis',
      'connection' => 'default',
      'queue' => 'default',
      'retry_after' => 5700,
  ],
];

horizon config:

'environments' => [
    'production' => [
      'supervisor-1' => [
        'connection' => 'redis',
        'queue' => [
          'default',
        ],
        'balance' => 'auto',
        'minProcesses' => 1,
        'maxProcesses' => 15,
        'tries' => 3,
      ],
    ],
];

Any help would be much appreciated!
