Laravel Not Writing Session To Memcached

I have 2 Memcached Servers e.g serv1 and serv2 Both Work Fine

But when i use it with Laravel Cache,

It works fine when i use serv1.

But when i change the server to serv2. It does not write the Session

I use 1 server at a time. I change the servers IPs.

serv2 works fine when i store data manually and retrieve it, it only gives me issue when i am using it with Laravel.

Both Servers have Memcached Service Installed.

Laravel's code cannot be wrong as it works on serv1.

I cant seem to figure out the problem, been a week since this issue.

Laravel version is 5.6. OS is CentOs THis is my Laravel's Cache.php

the servers are in my env file

'memcached' => [

        'driver' => 'memcached',
        'persistent_id' => env('MEMCACHED_PERSISTENT_ID'),
        'sasl' => [
            env('MEMCACHED_USERNAME'),
            env('MEMCACHED_PASSWORD'),
        ],
        'options' => [
            // Memcached::OPT_CONNECT_TIMEOUT  => 2000,
        ],
        'servers' => [
            [
                'host' => env('MEMCACHED_HOST', '127.0.0.1'),
                'port' => env('MEMCACHED_PORT', 11211),
                'weight' => 100,
            ],

I have used serv2 to store sessions from vanilla PHP and it is working fine there.
